Parsifal bell

Last updated

A Parsifal bell (German: Glockenklavier, "bell piano") is a stringed musical instrument designed as a substitute for the church bells that are called for in the score of Richard Wagner's opera Parsifal . [1]

Contents

The instrument was designed by Felix Mottl, a conductor of Wagner's works, and constructed by Schweisgut, of Karlsruhe, Germany. [1]

Construction

It is constructed on the principle of the grand piano. A massive frame is shaped like a snooker table. The instrument has five notes; each note has six strings (three are tuned to the fundamental pitch, and three an octave higher). The strings are struck by large hammers, covered with cotton-wool, which the performer sets in motion by a strong elastic blow from their fist, [2] similar to the motion of playing a carillon.

The hammers are attached to arms 22 inches (56 cm) long, which are screwed to a strong wooden span bridge placed horizontally above the strings at about two-fifths of the length from the front. On the point of the arm is the name of the note, and behind this the felt ledge struck by the fist. Two belly bridges and two wrest-plank bridges, one set for each octave, determine the vibrating length of the strings, and the belly bridge, as in other stringed instruments, is the medium through which the vibrations of the strings are communicated to the soundboard. The arrangement of pegs and wrest-pins is much the same as on the piano. [3]

Need

Difficulties arise whenever a composer writes a piece for orchestra in which he calls for reproducing the effect of church bells. Well-known examples include 1812 Overture , The Golden Legend , Cavalleria Rusticana , Pagliacci , Rienzi , and Parsifal . The most serious difficulty of all arose in Parsifal, where the bells are called for in an extremely solemn scene with deep religious significance. If real church bells were used for the notes Wagner wrote, they would overpower the orchestra and ruin the solemn atmosphere on the stage. [3]

Earlier Wagnerian church bell substitutes

Various substitutes for bells were tried in vain, but no other instrument gave a tone similar to that of church bells. This is because a bell sound consists of rich harmonics composing the clang, plus two distinct simultaneous notes, first the tap tone, which gives the pitch, and the hum tone or lower accompanying note. The dignity and beauty of the bell tone depend on the interval separating the hum from the tap tone. [3]

A stringed instrument, similar to the Parsifal bell but having only four notes, was used at Bayreuth for the first performance of Parsifal in 1882, where it was combined with tam-tams or gongs in an attempt to replicate the sound of a church bell. The instrument was built by the Bayreuth-based pianoforte manufacturer Steingraeber & Söhne. After many trials the following combination was adopted as the best makeshift: [3]

  1. the stringed instrument with four keys;
  2. four tam-tams or gongs tuned to the pitch of the four notes composing the chime;
  3. a tuba, which plays the notes staccato in quavers to help make them more distinct;
  4. a fifth tam-tam, on which a roll is executed with a drumstick.

Modern church bell substitutes

In most orchestral music, tubular bells are used when a bell sound is called for.[ citation needed ] In another special case, a special peal of hemispherical bells was constructed for use in performances of Sir Arthur Sullivan's cantata, The Golden Legend . Struck with mallets, they produced both tap and hum tone. [3] But Parsifal presented a particular problem because the lowest of the Golden Legend bells was a minor tenth higher than the lowest note required for Parsifal, and the aggregate weight of the four bells was thousands of pounds.[ citation needed ]

Modern productions of Parsifal typically use a synthesized, or electronically recorded, church bell sound.[ citation needed ]

Hammered dulcimer percussion-stringed instrument

The hammered dulcimer is a percussion-stringed instrument which consists of strings typically stretched over a trapezoidal resonant sound board. The hammered dulcimer is set before the musician, who in more traditional styles may sit cross-legged on the floor, or in a more modern style may stand or sit at a wooden support with legs. The player holds a small spoon-shaped mallet hammer in each hand to strike the strings. The Graeco-Roman dulcimer derives from the Latin dulcis (sweet) and the Greek melos (song). The dulcimer, in which the strings are beaten with small hammers, originated from the psaltery, in which the strings are plucked.

Harmonic series (music) Sequence of frequencies

A harmonic series is the sequence of frequencies, musical tones, or pure tones in which each frequency is an integer multiple of a fundamental.

Musical tuning Terms for tuning an instrument and a systems of pitches

In music, there are two common meanings for tuning:

Piano Musical instrument

The piano is an acoustic, stringed musical instrument invented in Italy by Bartolomeo Cristofori around the year 1700, in which the strings are struck by wooden hammers that are coated with a softer material. It is played using a keyboard, which is a row of keys that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings.

<i>Parsifal</i> Opera by Richard Wagner

Parsifal is an opera in three acts by German composer Richard Wagner. It is loosely based on Parzival by Wolfram von Eschenbach, a 13th-century epic poem of the Arthurian knight Parzival (Percival) and his quest for the Holy Grail.

Harmonic

A harmonic is any member of the harmonic series. The term is employed in various disciplines, including music, physics, acoustics, electronic power transmission, radio technology, and other fields. It is typically applied to repeating signals, such as sinusoidal waves. A harmonic of such a wave is a wave with a frequency that is a positive integer multiple of the frequency of the original wave, known as the fundamental frequency. The original wave is also called the 1st harmonic, the following harmonics are known as higher harmonics. As all harmonics are periodic at the fundamental frequency, the sum of harmonics is also periodic at that frequency. For example, if the fundamental frequency is 50 Hz, a common AC power supply frequency, the frequencies of the first three higher harmonics are 100 Hz, 150 Hz, 200 Hz and any addition of waves with these frequencies is periodic at 50 Hz.

An nth characteristic mode, for n > 1, will have nodes that are not vibrating. For example, the 3rd characteristic mode will have nodes at L and L, where L is the length of the string. In fact, each nth characteristic mode, for n not a multiple of 3, will not have nodes at these points. These other characteristic modes will be vibrating at the positions L and L. If the player gently touches one of these positions, then these other characteristic modes will be suppressed. The tonal harmonics from these other characteristic modes will then also be suppressed. Consequently, the tonal harmonics from the nth characteristic modes, where n is a multiple of 3, will be made relatively more prominent.

Overtone

An overtone is any frequency greater than the fundamental frequency of a sound. Using the model of Fourier analysis, the fundamental and the overtones together are called partials. Harmonics, or more precisely, harmonic partials, are partials whose frequencies are numerical integer multiples of the fundamental. These overlapping terms are variously used when discussing the acoustic behavior of musical instruments. The model of Fourier analysis provides for the inclusion of inharmonic partials, which are partials whose frequencies are not whole-number ratios of the fundamental.

String instrument Class of musical instruments with vibrating strings

String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when the performer plays or sounds the strings in some manner.

Crwth

The crwth, also called a crowd or rote, is a bowed lyre, a type of stringed instrument, associated particularly with Welsh music and with medieval folk music of England, now archaic but once widely played in Europe. Four historical examples have survived and are to be found in St Fagans National Museum of History (Cardiff), National Library of Wales (Aberystwyth), Warrington Museum & Art Gallery, and the Museum of Fine Arts, Boston (US).

Inharmonicity

In music, inharmonicity is the degree to which the frequencies of overtones depart from whole multiples of the fundamental frequency.

Piano acoustics are the physical properties of the piano that affect its sound. It is an area of study within musical acoustics.

Aliquot stringing

Aliquot stringing is the use of extra, un-struck strings in the piano for the purpose of enriching the tone. Aliquot systems use an additional string in each note of the top three piano octaves. This string is slightly higher than the other three strings so that it is not struck by the hammer. Whenever the hammer strikes the three conventional strings, the aliquot string vibrates sympathetically. Aliquot stringing broadens the vibrational energy throughout the instrument, and creates an unusually complex and colorful tone.

Piano tuning

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.

In music, a chorus effect occurs when individual sounds with approximately the same time, and very similar pitches, converge and are perceived as one. 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.

Bass guitar tuning

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 or videos introduce one or more tuning techniques, such as:

3rd bridge

The 3rd bridge is an extended playing technique used on the electric guitar and other string instruments that allows a musician to produce distinctive timbres and overtones that are unavailable on a conventional string instrument with two bridges. The timbre created with this technique is close to that of gamelan instruments like the bonang and similar Indonesian types of pitched gongs.

A third bridge can be devised by inserting a rigid preparation object between the strings and the body or neck of the instrument, effectively diving the string into distinct vibrating segments.

Steingraeber & Söhne

The piano manufacturer Steingraeber & Söhne is a German maker of upright and grand pianos. This family-owned business has its headquarters in Steingraeber Haus, a historic Rococo palace in Bayreuth. Udo Schmidt-Steingraeber is the sixth generation of Steingraebers to lead the family business.

Tromba marina

A tromba marina, marine trumpet or nuns' fiddle, is a triangular bowed string instrument used in medieval and Renaissance Europe that was highly popular in the 15th century in England and survived into the 18th century. The tromba marina consists of a body and neck in the shape of a truncated cone resting on a triangular base. It is usually four to seven feet long, and is a monochord. It is played without stopping the string, but playing natural harmonics by lightly touching the string with the thumb at nodal points. Its name comes from its trumpet like sound due to the unusual construction of the bridge, and the resemblance of its contour to the marine speaking-trumpet of the Middle Ages.

The strike tone, strike note, or tap note, of a percussion instrument when struck, is the dominant note perceived immediately by the human ear. It is also known as the prime or fundamental note. However, an analysis of the bell's frequency spectrum reveals that the fundamental only exists weakly and its dominance is a human perception of a note built up by the complex series of harmonics that are generated. The correct and accurate harmonic tuning is therefore important in creating a good strike tone.

Music technology (mechanical)

Mechanical music technology is the use of any device, mechanism, machine or tool by a musician or composer to make or perform music; to compose, notate, play back or record songs or pieces; or to analyze or edit music. The earliest known applications of technology to music was prehistoric peoples' use of a tool to hand-drill holes in bones to make simple flutes. Ancient Egyptians developed stringed instruments, such as harps, lyres and lutes, which required making thin strings and some type of peg system for adjusting the pitch of the strings. Ancient Egyptians also used wind instruments such as double clarinets and percussion instruments such as cymbals. In Ancient Greece, instruments included the double-reed aulos and the lyre. Numerous instruments are referred to in the Bible, including the horn, pipe, lyre, harp, and bagpipe. During Biblical times, the cornet, flute, horn, organ, pipe, and trumpet were also used. During the Middle Ages, hand-written music notation was developed to write down the notes of religious Plainchant melodies; this notation enabled the Catholic church to disseminate the same chant melodies across its entire empire.
