2014-03-09 15:05 Are questions about playing specific musical instruments within the scope of this science competition? For example: "What is a technique of the left hand and arm in which the pitch of a note varies in a pulsating rhythm?"

No. Rule 4.d.i clearly states questions are on general acoustic knowledge and the types of instruments brought by the competitors. Musical technique questions are are out of the realm of the rules UNLESS they are referring to WHY a technique makes that sound (i.e. how does the speed of the bow/air affect the sound - bowing/blowing faster is louder, why does vibrato change the sound).
