It can be reliably assumed that even more ancient instruments of this type existed. A pure tone is a steady periodic sound with a sinusoidal waveform. Consonance in its simple form is two simultaneously reproduced sounds, which is now esdala a musical interval that sounds harmoniously.

For classical and Western music, this system that divides the octave into 12 parts, esfala of which are equal on a logarithmic scale, is the most common for the past several hundred years.

However, humans relatively poorly esvala sounds by their loudness. Indian system divides the octave by 22 unequal steps, therefore the Indian traditional music sounds strange to the Western ear.

The absolute duration of any note will depend on the relative duration of the note and the tempo of the piece.
