Last updated Maria GloriosaThe Erfurt bell (1497) or any well-tuned bell: strike note on E, with hum note an octave below, minor third, fifth, octave or nominal, and major third and perfect fifth in the second octave.
Maria Gloriosa, or the Erfurt Bell, is a well-known bell of Erfurt Cathedral, cast by Geert van Wou in 1497. The world's largest medieval free-swinging bell,[3] it is now swung electrically. It was welded in 1985 to repair a crack, then, in August 2004, the bell was re-fused due to another crack from 2001.
Diameter: 8feet 5+3⁄4inches [2,584mm], weight: 13 tons 15 cwts. [12555kg], note: E [1497 standard].[1] Alternately: 2570mm, 11450kg, note by today's standards: F−.[4] It is about 2 meters tall.[5]
As with any well-tuned bell the hum tone is near an octave below the strike tone, and all other notes are in tune including the minor third, fifth, octave, and major third and fifth in the second octave that may be heard in large bells.

An equal temperament is a musical temperament or tuning system that approximates just intervals by dividing an octave into steps such that the ratio of the frequencies of any adjacent pair of notes is the same. This system yields pitch steps perceived as equal in size, due to the logarithmic changes in pitch frequency.
In music, there are two common meanings for tuning:
Meantone temperaments are musical temperaments; that is, a variety of tuning systems constructed, similarly to Pythagorean tuning, as a sequence of equal fifths, both rising and descending, scaled to remain within the same octave. But rather than using perfect fifths, consisting of frequency ratios of value , these are tempered by a suitable factor that narrows them to ratios that are slightly less than , in order to bring the major or minor thirds closer to the just intonation ratio of or , respectively. A regular temperament is one in which all the fifths are chosen to be of the same size.
In music theory, an interval is a difference in pitch between two sounds. An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord.
A carillon ( KARR-ə-lon, kə-RIL-yən) is a pitched percussion instrument that is played with a keyboard and consists of at least 23 bells. The bells are cast in bronze, hung in fixed suspension, and tuned in chromatic order so that they can be sounded harmoniously together. They are struck with clappers connected to a keyboard of wooden batons played with the hands and pedals played with the feet. Often housed in bell towers, carillons are usually owned by churches, universities, or municipalities. They can include an automatic system through which the time is announced and simple tunes are played throughout the day.
Campanology is the scientific and musical study of bells. It encompasses the technology of bells—how they are founded, tuned and rung—as well as the history, methods, and traditions of bellringing as an art.
A bell is a directly struck idiophone percussion instrument. Most bells have the shape of a hollow cup that when struck vibrates in a single strong strike tone, with its sides forming an efficient resonator. The strike may be made by an internal "clapper" or "uvula", an external hammer, or—in small bells—by a small loose sphere enclosed within the body of the bell.
In music theory, an enharmonic scale is a very ancient Greek musical scale which contains four notes tuned to approximately quarter tone pitches, bracketed between four fixed pitches. For example, in modern microtonal notation, one of the several enharmonic scales aligned with the conventional key of C major would be
A handbell is a bell designed to be rung by hand. To ring a handbell, a ringer grasps the bell by its slightly flexible handle – traditionally made of leather, but often now made of plastic – and moves the arm to make the hinged clapper strike the inside of the bell. An individual handbell can be used simply as a signal to catch people's attention or summon them together, but handbells are also often heard in tuned sets.
Piano tuning is the process 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.
Scientific pitch notation (SPN), also known as American standard pitch notation (ASPN) and international pitch notation (IPN), is a method of specifying musical pitch by combining a musical note name and a number identifying the pitch's octave.
Pummerin is the name of the bell in the Stephansdom, St. Stephen's Cathedral, in Vienna.
In music, 19 equal temperament, called 19 TET, 19 EDO, 19-ED2 or 19 ET, is the tempered scale derived by dividing the octave into 19 equal steps. Each step represents a frequency ratio of 19√2, or 63.16 cents.
Bellfounding is the casting and tuning of large bronze bells in a foundry for use such as in churches, clock towers and public buildings, either to signify the time or an event, or as a musical carillon or chime. Large bells are made by casting bell metal in moulds designed for their intended musical pitches. Further fine tuning is then performed using a lathe to shave metal from the bell to produce a distinctive bell tone by sounding the correct musical harmonics.
The bourdon is the heaviest of the bells that belong to a musical instrument, especially a chime or a carillon, and produces its lowest tone.
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.
Erfurt Cathedral, also known as St Mary's Cathedral, is the largest and oldest church building in the Thuringian city of Erfurt, central Germany. It is the episcopal seat of the Roman Catholic Diocese of Erfurt. The cathedral was mainly built in the International Gothic style and is located on a hillside overlooking the main town square, directly next to St Severus' Church. As a unique architectural ensemble, both churches together form the city's landmark. Former German names include Marienkirche and Propsteikirche Beatae Mariae Virginis.
Petersglocke, commonly referred to as Dicker Pitter, is the largest bell in Cologne Cathedral. It was cast in 1923 by Heinrich Ulrich in Apolda and hangs in the belfry of the south tower. With a weight of approximately 24,000 kilograms (53,000 lb), a clapper weighing about 700 kilograms (1,500 lb) and a diameter of 322 centimetres, it is the second largest freely swinging ringable bell in the world, after the bell of the People's Salvation Cathedral in Bucharest, Romania.
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.
Geert van Wou was a well-known Dutch bellfounder. He is best known today for the Maria Gloriosa (1497) of Erfurt Cathedral. The son of a bellfounder, he is considered one of the most important bellfounders of the Middle Ages, though records suggest he participated in other casting.
