Naad

Naad
Music is related to sound and
sounds are of two types. First
which that is used for music and
second is, That which cannot be
used for music. The sound
which can be used for music is
called Naad and the sound
which cannot be used for music
is called noise. In short we can
say that a sound with a constant
vibration is called as swar and
this is the sound that comes in
use of music, with sounds
melodious to ears and gives joy
to our soul. This sound in
Hindustani classical music is
called Naad.
