Bass (sound)

Bass ( BAYSS) (also called bottom end) describes tones of low (also called "deep") frequency, pitch and range from 16 to 250 Hz (C0 to middle C4) and bass instruments that produce tones in the low-pitched range C2-C4. They belong to different families of instruments and can cover a wide range of musical roles. Since producing low pitches usually requires a long air column or string, and for stringed instruments, a large hollow body, the string and wind bass instruments are usually the largest instruments in their families or instrument classes.
