I'm trying to figure out whether it's appropriate to use "percussion" or "percussions" in the following sentences:
- A break can be any musical segment (typically four measures or less), even if it doesn't contain percussions/percussion.
- Drum breaks, breaks, or breakbeats are percussions-only/percussion-only passages typically found in funk, soul, and jazz recordings.
I'm leaning towards the plural because:
- You would say "This is a members-only event".
- As seen here (http://www.orsymphony.org/edu/instruments/woodwinds.aspx), you say "the woodwind family", but "the mouthpieces for some woodwinds".
I want to label certain objects as being either "percussion(s)-only" or "not only percussion(s)", and would therefore appreciate answers which adhere to this usage, rather than suggesting a more verbose alternative.
