What is difference between loundess and pitch?

Answer 1

I'll use a few common instruments for example. On a piano, pitch would be which key you hit. The keys on the right will create a higher pitch while the left keys will create a lower pitch. The volume merely depends on how hard the key is hit. It is possible to have loud or quiet notes of any pitch. On a guitar, the higher the fret the higher the note, while volume depends on the force of the strumming. For drums, the pitch would depend on the size of the drum; the larger the drum, the lower the pitch. Volume would depend on how hard the drum is hit.
