These instruments are sound synthesizers that use mechanical, optical, or other forms of non-electric computation, sampling, processing, or the like. It has been proposed that music synthesizers that perform computation, and/or that work by recording and playback of sound samples, or the like, be referred to as quintephones.
The orchestra is divided into four groups (five if a keyboard instrument is used) and specified as follows: [1] Woodwind instruments: flutes, oboes, clarinets, saxophones (if one or more are needed), bassoons; Brass instruments: horns, trumpets, trombones, tubas; Percussion: timpani, snare drum, bass drum, chimes, etc.
The Hornbostel–Sachs system of musical instrument classification groups all instruments in which sound is produced through vibrating air. This can include a column of air being set in vibration (as in wind instruments) or an air-flow being interrupted by an edge (as in free-reeds).
For example, a perfect fifth, say 200 and 300 Hz (cycles per second), causes a listener to perceive a combination tone of 100 Hz (the difference between 300 Hz and 200 Hz); that is, an octave below the lower (actual sounding) note. This 100 Hz first-order combination tone then interacts with both notes of the interval to produce second-order ...
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
The criteria for classifying musical instruments vary depending on the point of view, time, and place. The many various approaches examine aspects such as the physical properties of the instrument (shape, construction, material composition, physical state, etc.), the manner in which the instrument is played (plucked, bowed, etc.), the means by which the instrument produces sound, the quality ...
In these cases, the waveform is an attribute that is independent of the frequency, amplitude, or phase shift of the signal. The waveform of an electrical signal can be visualized in an oscilloscope or any other device that can capture and plot its value at various times, with suitable scales in the time and value axes.
For example, some authorities regard families as encompassing only instruments of different pitch range that have similar construction and tone quality. They therefore, for example, do not regard the cor anglais as a member of the oboe family, because its narrow bore and piriform bell give it a distinctly different tone quality from the oboe.
