In a typical keyboard layout, black note keys have uniform width, and white note keys have uniform width and uniform spacing at the front of the keyboard. In the larger gaps between the black keys, the width of the natural notes C, D and E differ slightly from the width of keys F, G, A and B.
The Harmonic Table keyboard layout was used in a keyboard harmonica called the Harmonetta, [2] invented by Ernst Zacharias [3] and manufactured by Hohner from the early 1950s through the mid-1970s. A similar keyboard was developed by Larry Hanson [ 4 ] in 1942 for use with a 53 tone scale but turns the fifth sideways and the major third to the ...
The most common of these are the piano, organ, and various electronic keyboards, including synthesizers and digital pianos. Other keyboard instruments include celestas , which are struck idiophones operated by a keyboard, and carillons , which are usually housed in bell towers or belfries of churches or municipal buildings.
Like the glockenspiel, the xylophone is a transposing instrument: its parts are written one octave below the sounding notes. [5] Concert xylophones have tube resonators below the bars to enhance the tone and sustain. Frames are made of wood or cheap steel tubing: more expensive xylophones feature height adjustment and more stability in the stand.
The note C 4 written down produces: Comment Accordion: D ♭ piano accordion D ♭ 4: Bass accordion: C 2: Arpeggione: C 2 /C 3: Bagpipe Great Highland bagpipe: variable D ♭ 4 - D 4: A minority of bagpipes, made for playing with other instruments, are exactly D ♭ 4 (referred to as B ♭, relative to the tonic note A rather than C).
In most musical instruments, the tone-generating component (a string or resonant column of air) vibrates at many frequencies simultaneously: a fundamental frequency that is usually perceived as the pitch of the note, and harmonics or overtones that are multiples of the fundamental frequency and whose wavelengths therefore divide the tone-generating region into simple fractional segments (1/2 ...
Despite the name, keyboard instruments such as the celesta and keyboard glockenspiel are not considered keyboard percussion instruments, despite being idiophones, due to the different skillsets required to play them. This is because keyboard percussion instruments do not possess actual keyboards, but simply follow the arrangement of the ...
An isomorphic keyboard is a musical input device consisting of a two-dimensional grid of note-controlling elements (such as buttons or keys) on which any given sequence and/or combination of musical intervals has the "same shape" on the keyboard wherever it occurs – within a key, across keys, across octaves, and across tunings.
