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.
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.
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 ...
Resonance causes a vibrating string to produce a sound with constant frequency, i.e. constant pitch. If the length or tension of the string is correctly adjusted, the sound produced is a musical tone. Vibrating strings are the basis of string instruments such as guitars, cellos, and pianos.
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 ...
In sound and music, an envelope describes how a sound changes over time. For example, a piano key, when struck and held, creates a near-immediate initial sound which gradually decreases in volume to zero. An envelope may relate to elements such as amplitude (volume), frequency (with the use of filters) or pitch.
Examples of exceptions include the circular drum – a timpano whose first overtone is about 1.6 times its fundamental resonance frequency, [5] gongs and cymbals, and brass instruments. The human vocal tract is able to produce highly variable amplitudes of the overtones, called formants , which define different vowels .
