Dear Mohammad,

Here is a similar discussion.

You should watch video of famous nobelist Richard Feynman on this subject. Here is a segment of the video:

He explains his wise view on the perception of beauty of scientists vs artist. 

The knowledge of acoustics and mathematics is important for a musician.

Allow to know and explain a series of phenomena associated with the perception of the sound/music, musical performance and musical composition.

Depending on the type of musical composition, the mathematical knowledge can be associated to pure inspirations.

I agree with Carlos that depending on the type of music and nature of musical genre and the approach of the musician in his/her creation process one may benefits from math and physics; concrete music is an example of that.

Dear Mats,

Just as an example in the context of the phenomena associated with the perception of the sound /music, the musical consonance can be interpreted in the area of acoustics/mathematics.

The perfect musical intervals (octave, 2: 1, fifth, 3: 2, and fourth, 4: 3) correspond to frequency relations of small integers. These consonant intervals are among the first harmonics (frequency components) of a sound.

Good points Mates!
