Hey, atm I'm working on a physics project for school where we pick an instrument and answer questions about it that we'll have to present in class. I'm going to use a drum pad. The one question I'm stuck on is: I'm not sure if this would be right but please correct me if I'm wrong: For frequency, I was just going to play the same beat. For amplitude, I'm going to hit the pad harder to show a higher amplitude and softer for a lower amplitude. For resonance and overtone, I have no idea what to do. The definition I have for resonance is - occurs when small repeating forces are repeated at regular intervals to a vibrating or oscillating object and the amplitude increases. The definition I have for overtone is - A musical tone that is a part of the harmonic series above a fundamental note and may be heard with it. I am really clueless on this and any help would be great.
