marimba and xylophone and other instruments

[Pierre Abbat <phma@phma.optus.nu>]

Yesterday two men played a marimba at church, and I thought of what to call it 
in Lojban. {amrimba} is a valid fu'ivla, but for xylophones in general, I'm 
not so sure. Does {mudjanbypi'o} make sense?

What exactly is a pipno? Does any instrument with something arranged like a 
piano keyboard qualify, or do they have to be keys?

{damri} according to the gimste includes cymbals and gongs as well as drums. 
Cymbals and gongs are idiophones, and cymbals are held at the center; drums 
are membranophones held at the outside. Hornbostel-Sachs classifies bells, 
cymbals, and gongs all as 111 and most drums as 21.
