Sound is a sequence of waves of pressure, which propagates through compressible media such as air or water or solid. During their propagation, waves can be reflected,
ULTRASOUND. FIND OUT MORE. Sound can be low-pitched, like the rumble of a large truck, or high-pitched, like a whistle. The pitch of a sound depends on the frequency of its wave. Piano keys produce notes that increase in pitch from the left side of the keyboard to the right. We can hear sounds of different pitches, but there are some sounds we cannot hear.

We know music by itself has an effect on people. From low chords to high chords, from fast beats to slow beats, music has an impact on behavior. Music in general tends to reduce or delay fatigue (Diserens 260).Music has been proven to increase muscular endurance (Diserens 274).usic has no definite effect on precision or accuracy of movement, if the rhythm is not adapted to the rhythm of the work (Diserens 261). Music has been shown to reduce accuracy in typewriting and handwriting, the results being shown in a increased number of errors (Diserens 262).
