For questions about generalities about instruments or groups of instruments.
Technical questions about an instrument, not how to play or practice it.
For example:
- Why is a violin shaped the way it is?
- Why can only a limited set of tones be bent on a harmonica?
- How does the size of a mouthpiece relate to its name?
- How does the type of wood used for a piano influence its sound?
Not:
- How do I use a bow?
- How do I bend a tone on the harmonica?
- Which mouthpiece size is best for playing high tones?
- What wood type is best for my home piano?
