what is a concertina made out of?

[ohako]

concertina: miniature-ish accordion, probably a good stand-in for a 3 lb instrument that relies on Perform (keyboard) to use.

materials: wood for the side boards, cloth and leather for the bellows, and brass or steel for the reeds.

So, for an 8 Str bard, every pound matters. For the purposes of making a concertina or accordion out of a special material, which one is it: mithral, darkwood, or darkleaf cloth?

Could I assume that each kind of part weighs 1 lb, and price it accordingly? 500gp for the mithral reeds, 375gp for darkleaf bellows, and...I dunno, 110gp for darkwood boards?

also, what the heck, Occult Adventures introduced the concept of a 'silver' masterwork instrument, where the body, or possibly the strings, of an instrument are made of silver.

a) can you make a silver flute out of mithral or singing steel?
b) can you make the body of a lute out of darkwood, and just string it with silver?

[Fabius Maximus]

The Silver Balladeer archetype was inspired by the character John the Balladeer from the stories of Manly Wade Wellman. John carries a guitar with silver strings. (Stringing instruments with silver is also mentioned in the archetype's description.)

Sounds reasonable for a home game. For PFS... *shrug*

A silver balladeer gains the bardic performances listed below. These bardic performances all require the use of a silver or silver-stringed instrument, which costs twice as much as a normal masterwork instrument.

To determine the price of a darkwood item, use the original weight but add 10 gp per pound to the price of a masterwork version of that item.

So I'd guess a silver-stringed darkwood lute should cost twice the same as a normal instrument plus 10gp per pound.

I'd say no on the flute since it's only one material - though it's a bit odd that a mithral or singing steel weapon counts as alchemical silver but a mithral or singing steel instrument doesn't count as a silver instrument. I'd probably house-rule that as a GM.
