Peterson Electro-Musical Products, Inc. is a music-electronics company founded by Richard H. Peterson in 1948. The company introduced the first commercial handheld electronic tuner for musicians, the Model 70, in 1964, and later its models of strobe tuners became popular among touring and studio musicians such as the Grateful Dead, The Who, Pink Floyd, Queen, Frank Zappa, Jimi Hendrix, and Neil Young.[1]
Richard H. "Dick" Peterson founded Peterson Electro-Musical Products in 1948.[1] He soon licensed his inventions to the Gulbransen Piano Company of Chicago to use in home electronic organs. In 1957, Peterson completed the world's first transistor organ for Gulbransen.[2] The company went on to produce other products for musical tuning, electronic organs, home security, and keyboards, and later developed and produced electronic and electro-mechanical equipment used in pipe organs.[1]
In 1964, the company built a new 3,000-square-foot (280m2) headquarters in Alsip, Illinois, on a plot of 2.5 acres (10,000m2). They built two additional buildings totaling 15,000 square feet (1,400m2) on the company site between 1975 and 1977.[2]
In 1985, the company acquired Conn Tuner and continued to service the Strobotuner product line, which is now made in China.[1]
In 1991 Dick Peterson's son Scott R. Peterson became Company President, after previously serving as Design Engineer, Production Manager, and Vice President.[2]
In 1998, the Peterson Company celebrated its 50th anniversary by creating the "Beer Bottle Organ" prototype in the exhibit area of the American Institute of Organ Builders convention. The "BBO" used pipe organ components and beer bottles with liquid, precisely tuned with a Peterson strobe tuner, to produce a clear, flute-like musical sound when played with a keyboard or via recorded MIDI files.[2] Peterson Electro-Musical Products, Inc. is still family owned, and still has an active research and development program for tuner and pipe organ-equipment product lines.[2]
Tuner product history
The first Peterson tuner, the Model 150, was released in 1952, after Peterson developed it for their own use in tuning organs. The Model 150, and the Model 200 released in 1959 were the first products to carry the Peterson name.[2] These tuners used vacuum tube technology and produced a wide range of finely adjustable audio tones. The design advanced to solid state with the Model 300 in 1966.[1]
Peterson engineer Bill Hass (born February 6, 1939, died May 3, 2008), built the first commercially available battery-powered handheld tuner, the Model 70, in 1964. The Model 70 was a chromatic tuner that generated twelve fixed pitch reference tones. The user tuning an instrument set the tuner to a pitch and matched the tone.[1]
In 1967, Peterson introduced its first strobe tuner, the Model 400. It was the first solid-state strobe tuner on the market, and did not require calibration. Musicians could select one-cent increments. The tuner was highly influential in Peterson Tuner's growing presence in the fledgling tuner industry.
Peterson Model 520 Strobe Tuner
The rise of popular music as a business force in the 1960s and 1970s brought increased demand for professionalism in performance and recording. The only commercially available tuners in that era were manufactured by Peterson and Conn, which led to their presence on most major records and live concerts. The Peterson models became highly popular among leading touring and studio musicians, and were frequently used onstage by such bands as the Jimi Hendrix Experience, The Rolling Stones, Grateful Dead, The Who, Pink Floyd, Frank Zappa and the Mothers of Invention, Queen, Neil Young and Crazy Horse, the Bruce Springsteen Band, and many others.[1] The tuner also became popular for precision tuning by school bands, top-level orchestras, and musical instrument manufacturers.[1][2]
In 1980 Peterson introduced the Model 100 tuner—designed exclusively for guitars. The tuner used the strobe concept to create a rolling LED display that indicated pitch error by the speed of the rolling LEDs. The Model 100 sold successfully in the early 1980s and stayed on the market for nearly a decade.[1]
In the 1990s, Peterson made the first significant change to the spinning wheel strobe since the late 1960s. They introduced the "Strobe Center 5000", which used twelve microprocessor-controlled digital stepper motors—one motor for each note in an octave. The strobe can change keys and temperaments, can store stretch tuning tables in a memory bank, and is a true polyphonic tuner.[1] Widely used by school bands for its visibility and by instrument makers for its ability to show harmonic content, the Strobe Center 5000 remains Peterson's flagship strobe tuner.
After the Strobe Center 5000, Peterson Tuners re-designed their mechanical strobe tuning line and introduced a line of AutoStrobe series tuners. These selected the note automatically and offered programmability for advanced users. Besides the Strobe Center 5000, the AutoStrobe tuners are the only mechanical strobe tuners still made.[1] Models include the AutoStrobe 490, 490ST, and 590.
Virtual Strobe product line
In 2001, Peterson Tuners developed a line of Virtual Strobe electronic strobe tuners that use a LCDdot-matrix display to emulate a mechanical strobe disc wheel, creating a stroboscopic effect. Peterson began using the "Strobo" name for all of its new Virtual Strobe line of products. According to the company, this was a response to other manufacturers using the word "strobe" for non-strobe tuners. The Peterson 'strobo' tuner line guarantees 1/10th cent accuracy,[3] or higher by using patented technology.[4] Peterson claims the Virtual Strobe display delivers higher resolution than needle or LED-based tuners.[1]
Peterson Sweetened Tunings
Peterson Virtual Strobe tuners offer specialized tuning solutions for various instruments, referred to by Peterson Tuners as sweeteners. According to Peterson, "sweetening" a tuning means using consonance and dissonance to affect the sound of a specific instrument, ultimately aiding creation of tension and release in music.
Peterson strobe tuners are loaded with presets that see a particular tuning as a group of notes (not just individual pitches) and, because of their high tuning resolution, can optimize the notes within these groups, making them more consonant with one another.
Peterson coined sweetening to distinguish between temperaments and other exclusive sets of offsets. A temperament, by definition, implies the use of no more than 12 offsets, one for each pitch in the 12-tone chromatic scale. These offsets form a "template" octave. C0, C1, C2 through C8 for example, all have the same cent offset defined for C.
Peterson "sweetened" presets are not temperaments because they do not necessarily pertain to a scale. They are sets of offsets for a particular instrument. The GTR sweetener, for example, accommodates the specific, common tuning problems inherent to a 6-string guitar. Unlike temperaments, the sweetener offsets only have musical benefit when applied to their intended instrument.[1]
In 2001, Peterson introduced the model "VS-I" Virtual Strobe Tuner. The VS-II in 2003 had an improved display, additional features, and "sweetened" tunings. According to Peterson, it was also the first tuner to recognize and introduce dedicated tempered tuning presets for pedal steel guitar players. The V-SAM model, introduced later that year, added an audio output speaker and a metronome to the feature set of the popular VS-II.[1] The VS-II was superseded by the StroboFlip in 2006.
A StroboStomp tuner
In 2004, Peterson released the Virtual Strobe tuner model as a stomp box format. The StroboStomp2 replaced the first model in 2007.[1] Both models of the StroboStomp featured true-bypass technology that would not 'color' the tone of the connected instrument and offered a studio-grade, on-board DI (direct injection box). The StroboStomp was discontinued in 2007. The StroboStomp2 was discontinued in 2009 and replaced by the VSS-C Stomp Classic. The StroboStomp, according to Peterson, was the first true-bypass tuner and the first strobe pedal tuner available commercially.
A VS-F StroboFlip tuner
In 2006, the VS-II was replaced with the StroboFlip, a smaller version that could be used by musicians without a pedal board. It featured an innovative "Pitch Holder" that connected to the tuner with a tripod-like mount, allowing it to clamp onto music or mic stands. It is also the first tuner to specify the correct interval tunings for resophonic guitar and orchestral strings.[1]
In 2007, the StroboRack was introduced and featured a large 7" tuning display that made it easily visible from a variety of angles and environments.[1] The StroboRack is the world's first single-space rack-mount strobe tuner.
StroboSoft 1.0 software screenshot
In late 2005, Peterson Tuners announced the release of the StroboSoft, a software based strobe tuner that can be used on Mac or PC to tune on your computer. StroboSoft provides the same tuning accuracy as the hardware products and can be used as a stand-alone tuner or as a VST/AU (StroboSoft 2.0) plug-in. The software package contains utilities for tuning and sound analysis, including a spectrum analyzer, oscilloscope, and linear pitch graph.[5]
In 2008, Peterson released its first standalone metronome called the BB-1 BodyBeat, a small battery-operated device which, in addition to displaying and sounding the beat, also included a vibrating clip. This clip, called the "Vibe Clip" enabled the metronome to operate silently, transmitting the tempo via a tactile pulse felt by the user when the vibe clip was worn close to the body. The BB-1 was superseded in 2011 by the BBS-1 BodyBeat Sync which expanded upon the concept by adding a more powerful metronome engine, wireless synchronizing of multiple units and the ability to store midi tempo maps. In 2016 Peterson release the BodyBeat Pulse Solo, a vibing/tactile metronome that plugs into any audio metronome that has a 3.5mm headphone out jack including metronome apps. The BodyBeat Pulse converts the audio to a pulse and has a built-in rechargeable battery to power it.
A StroboClip tuner
In 2010, the Stomp Classic replaced the prior StroboStomp2 product and added an improved DI, a larger display and multi-octave programmability. The stomp box design was also redesigned and modeled after the 1970s Conn ST-11 Strobotuner. It can connect to a computer via USB, and accepts altered tunings and sweeteners created on a special software editor made especially for the tuner.
The StroboClip, introduced in 2010, is a clip-on strobe tuner. It contains preset sweetened tunings for a variety of acoustic instruments, but can be used for electric guitar and bass players during on-stage performance. According to Peterson, the StroboClip was the first hardware tuner to feature the correct interval tuning for not just guitars and basses, but also for such diverse instruments as bagpipes, oud, banjo, sitar and Arabic maqamat (Eastern temperaments).
Peterson Tuners released a Virtual Strobe tuning application in 2009 as a professional-grade tuning app for Apple's iPhone and iPod Touch. The application leverages the Virtual Strobe display and provides chromatic tuning with Peterson's renowned standard tuning resolution of 0.1 cent. In 2010, Peterson released a native iPad version that offers unique functions on the iPad platform that includes VGA output support for classroom usage and manual note selection. An adaptor cable designed specifically for use with the Apple devices was also introduced to support the app and offer users an entry-level package solution. As of July 14, 2015, Peterson has renamed/created a new product for Apple devices called iStroboSoft.[citation needed]
In 2014, an in-app purchase of Petersons exclusive Sweetener library was added. The option of purchasing individual Sweeteners or instrument-based packs is offered. The addition of other tuning scope tools available as in-app purchases was also added including harmonic tuning, oscilloscope, spectrum waveform analyzer, and a full-color spectrogram.In 2013, a version of iStroboSoft was released for the Android market with a similar display to the iOS version and the same 1/10th cent accuracy. The Android version does not have the in-app Sweetener or tuning scope options.
2012 was marked by the release of the StroboPLUS HD with a menu of 90 Sweetened Tuning presets and temperaments for individual instruments. he addition of a computer-aided USB user interface called Peterson Connect allows users to configure their tuner to their own requirements including such controls such as strobe speed, pattern and backlight behaviors in addition to programming temperaments and Sweeteners. Notably, the StroboPLUS can be programmed with up to 128 target pitches in one preset, these pitches can be placed within one octave or spread over several octaves - as the user wishes, thus making it suitable for regular as well as microtonal tuning.
2019 marked the release of the StroboStomp HD. This pedal tuner has a smaller footprint than its predecessor the Stomp Classic but a much larger tuning display. The full-color LCD display allows assigning colors to the different settings for each instrument for easy recognition and to maximize viewing. The StroboStomp HD offers either pop-less true bypass, monitor mode, or a buffered output.
The bass guitar, electric bass or simply bass is the lowest-pitched member of the guitar family. It is a plucked string instrument similar in appearance and construction to an electric or acoustic guitar, but with a longer neck and scale length. The bass guitar most commonly has four strings, though five- and six-stringed models are also relatively popular, and bass guitars with even more strings or courses have been built. Since the mid-1950s, the bass guitar has largely come to replace the double bass in popular music due to its lighter weight, the inclusion of frets in most models, and, most importantly, its design for electric amplification. This is also due to the fact that the double bass is acoustically compromised for its range in that it's scaled down from the optimal size that would be appropriate for those low notes.
In music, there are two common meanings for tuning:
Meantone temperaments are musical temperaments, that is a variety of tuning systems, obtained by narrowing the fifths so that their ratio is slightly less than 3:2, in order to push the thirds closer to pure. Meantone temperaments are constructed similarly to Pythagorean tuning, as a stack of equal fifths, but they are temperaments in that the fifths are not pure.
The bouzouki is a musical instrument popular in Greece. It is a member of the long-necked lute family, with a round body with a flat top and a long neck with a fretted fingerboard. It has steel strings and is played with a plectrum producing a sharp metallic sound, reminiscent of a mandolin but pitched lower. It is the precursor to the Irish bouzouki, an instrument derived from the Greek bouzouki that is popular in Celtic, English, and North American folk music. There are two main types of Greek bouzouki: the trichordo (three-course) has three pairs of strings and the tetrachordo (four-course) has four pairs of strings. The instrument was brought to Greece in the early 1900s by Greek refugees from Anatolia, and quickly became the central instrument to the rebetiko genre and its music branches. It is now an important element of modern Laïko pop Greek music.
In music, inharmonicity is the degree to which the frequencies of overtones depart from whole multiples of the fundamental frequency.
GarageBand is a software application by Apple for macOS, iPadOS, and iOS devices that allows users to create music or podcasts. GarageBand was originally released for macOS in 2004 and brought to iOS in 2011. The app's music and podcast creation system enables users to create multiple tracks with pre-made MIDI keyboards, pre-made loops, an array of various instrumental effects, and voice recordings.
Piano tuning is the act of adjusting the tension of the strings of an acoustic piano so that the musical intervals between strings are in tune. The meaning of the term 'in tune', in the context of piano tuning, is not simply a particular fixed set of pitches. Fine piano tuning requires an assessment of the vibration interaction among notes, which is different for every piano, thus in practice requiring slightly different pitches from any theoretical standard. Pianos are usually tuned to a modified version of the system called equal temperament.
Chorus is an audio effect that occurs when individual sounds with approximately the same time, and very similar pitches, converge. While similar sounds coming from multiple sources can occur naturally, as in the case of a choir or string orchestra, it can also be simulated using an electronic effects unit or signal processing device.
The Polymoog is a hybrid polyphonic analog synthesizer that was manufactured by Moog Music from 1975 to 1980. The Polymoog was based on divide-down oscillator technology similar to electronic organs and string synthesizers of the time.
A microtuner or microtonal tuner is an electronic device or software program designed to modify and test the tuning of musical instruments with microtonal precision, allowing for the design and construction of microtonal scales and just intonation scales, and for tuning intervals that may differ from those of common Western equal temperament. The term also indicates a high-precision mechanical tuning device found on some vintage Conn brand brass and reed instruments. These were first introduced with their 1918 catalog and manufactured until about 1954. Such devices were also offered with some vintage saxophones manufactured in Europe by Beaugnier, Dolnet, Hüller, Keilwerth and other famous makers in the same period.
In music, an electronic tuner is a device that detects and displays the pitch of musical notes played on a musical instrument. "Pitch" is the perceived fundamental frequency of a musical note, which is typically measured in Hertz. Simple tuners indicate—typically with an analog needle or dial, LEDs, or an LCD screen—whether a pitch is lower, higher, or equal to the desired pitch. Since the early 2010s, software applications can turn a smartphone, tablet, or personal computer into a tuner. More complex and expensive tuners indicate pitch more precisely. Tuners vary in size from units that fit in a pocket to 19" rack-mount units. Instrument technicians and piano tuners typically use more expensive, accurate tuners.
This article describes the process and techniques involved in the tuning of a pipe organ. Electronic organs typically do not require tuning.
Music theory analyzes the pitch, timing, and structure of music. It uses mathematics to study elements of music such as tempo, chord progression, form, and meter. The attempt to structure and communicate new ways of composing and hearing music has led to musical applications of set theory, abstract algebra and number theory.
In musical tuning, a temperament is a tuning system that slightly compromises the pure intervals of just intonation to meet other requirements. Most modern Western musical instruments are tuned in the equal temperament system. Tempering is the process of altering the size of an interval by making it narrower or wider than pure. "Any plan that describes the adjustments to the sizes of some or all of the twelve fifth intervals in the circle of fifths so that they accommodate pure octaves and produce certain sizes of major thirds is called a temperament." Temperament is especially important for keyboard instruments, which typically allow a player to play only the pitches assigned to the various keys, and lack any way to alter pitch of a note in performance. Historically, the use of just intonation, Pythagorean tuning and meantone temperament meant that such instruments could sound "in tune" in one key, or some keys, but would then have more dissonance in other keys.
Generalized keyboards are musical keyboards, a type of isomorphic keyboard, with regular, tile-like arrangements usually with rectangular or hexagonal keys, and were developed for performing music in different tunings. They were introduced by Robert Bosanquet in the 1870s, and since the 1960s Erv Wilson has developed new methods of using and expanding them, proposing keyboard layouts including any scale made of a single generator within an "octave" of any size.
Each bass guitar tuning assigns pitches to the strings of an electric bass. Because pitches are associated with notes, bass-guitar tunings assign open notes to open strings. There are several techniques for accurately tuning the strings of an electric bass. Bass method or lesson books introduce one or more tuning techniques, such as:
In music, an interval ratio is a ratio of the frequencies of the pitches in a musical interval. For example, a just perfect fifth is 3:2, 1.5, and may be approximated by an equal tempered perfect fifth which is 27/12. If the A above middle C is 440 Hz, the perfect fifth above it would be E, at (440*1.5=) 660 Hz, while the equal tempered E5 is 659.255 Hz.
Roadie tuners are automatic stringed instrument tuners created and developed by the music-tech startup, Band Industries, Inc. Roadie 3, the last iteration in the Roadie tuner family is compatible with stringed instruments that have a guitar machine head including electric, acoustic, classical and steel guitars, 6-7-12 string guitars, ukuleles, mandolins and banjos. Roadie Bass is designed to tune bass guitars as well as the instruments Roadie 3 can tune.
The 12 Step foot controller is a bass pedal-style programmable MIDI controller pedal keyboard made by Keith McMillen Instruments which was released in 2011. It has small, soft, rubbery keys that are played with the feet. As a MIDI controller, it does not make or output any musical sounds by itself; rather, it sends MIDI messages about which notes are played to an external synth module or computer music program running on a laptop or other computer. Each key on the 12 Step senses the velocity, aftertouch pressure, and the amount of tilt the player is applying with his feet. The messages from the player's foot presses can be sent via USB to a computer-based virtual instrument or to a synthesizer or other electronic or digital musical instrument.
