In my years with the National Ballet Orchestra, we played “Sleeping Beauty” so many times that, when a blackout occurred in mid-performance, we just kept going (like the Energizer bunny, but perhaps not as cute). The cadenza is not my favourite of the three, with a rather unappealing repeat of a seventh chord, with left-hand turnarounds. It’s not as difficult or notey as Nutcracker or Swan Lake, but there are tricky bits here and there. Re: Britten: I’ll have to go have a look at that again! I think I just played the left hand straight and the right cracked, but simultaneously. Is the left hand supposed to come after the right?
