It's an odd one, because Trinity do not give much guidance on selection of pieces - and at this level, there is not much of a hike in difficulty of pieces from ATCL to LTCL; it's as if the recorder repertoire experiences a bit of a plateau, really. There is another huge jump up to FTCL, but at the intermediate level there is a lot of overlap. Four of the pieces I'd chosen were deemed suitable - I'd nicked a couple from the LRSM list, two from the LTCL one - and the fifth, which I'd not found any easier to learn than any of the others, was deemed to be of grade 8 difficulty only. It's on the dipABRSM list for flute, and often flute pieces will appear a level or two higher in the recorder repertoire. Trinity hadn't responded to my initial inquiry about this piece - they want a complete programme before they'll comment, I think. I really think they should publish previously accepted programmes; their repertoire list for ATCL is comprehensive and attractive, the LTCL one very short - only about 14 pieces in all, and a lot of overlap (eg, I'd not programme Uccellini with Castello because they're too similar in style).
There were other quibbles, one being that there wasn't enough balance because I had four baroque pieces and one 20thC - to be honest, I don't much care for programmes which contrast 20thC and baroque music anyway - it is very difficult to tie the pieces into each other in a way which doesn't jar. The 20thC one is based on a medieval dance tune, so it did tie in; the baroque pieces were all rather different from each other, and one was in any case early baroque, the rest later. If I have to learn a second 20thC piece, it'd almost certainly have to be an avant-garde one, because the likes of Staeps or Berkley doesn't really appeal that much to me; the worst thing about learning the avant-garde stuff though is the enormous length of time you need to spend learning how to do all the peculiar noises demanded - once I get that into my head, I usually find I can play the notes OK. The oddest quibble was that I'd programmed three treble pieces, one descant and one tenor - I'd been thinking three on an F instrument, two on C instruments - which probably reflects the balance of repertoire available for recorders anyway!
Recorders really are an exception in so many ways - no classical or romantic repertoire, and whereas you
may play a second member of a family of instruments for any of the other woodwind - so a piece on cor anglais in an oboe exam - for recorders I'm expected to balance the number of pieces evenly between members of the family

. That's even before looking at our dynamic range problem...
