19A is almost certainly QUARTET but can you please parse it for me?
"Chamber group with piano ousting one without skill"
(I can see skill=art as a possibility, but nothing else!)

[dannyk13]

Art (skill) inside qu(i)et

[mallyh]

piano = quiet oust i leaves quet + art

[novalis]

piano = quiet - 1 ( i ) round art,

[CrikeyMoses]

Ah! Wasted too much time thinking piano was 'p' and trying to find what that was missing from!
Thank you dannyk13, mallyh and novalis.

It's not a great clue - it requires 'without' as a preposition to mean 'outside', and in modern usage it doesn't (Chambers and Collins both show it as 'archaic'). The adverb form is fine as a 'container' indicator, so '...art having quiet without...' would be ok. I'm not too happy about the 'with' as a link word between solution and wordplay, either...
