For Nth London/Herts (ie Barnet
) you probably have Mill Hill County, QE Boys, Dame Alice and maybe Latymer. They all select various numbers for music with Mill Hill and DAO not requiring academic entrance passes unlike the other two.
Mill Hill and DAO have only a few places anyway and DAO you need to pass an initial aural (beep/tone) test before being called for music audition. You can look on their sites to see how few places there are and DAO in particular you may fall foul of the catchment rules.
Latymer requires grade 5 min which I think is tough as some instruments don't lend themselves to high grades at early ages. The music teacher also admitted to planning years in advance on requirements so if a particular instrument is required and your son plays it your luck is in. Although I suspect this is probably the agenda at most places anyway.
QE is pretty much as described. For Moose's benefit ie query in the other QE music thread. The boy ahead came out crying, mine came out crying, the one after came out crying. All for various reasons such as bringing a piece for a non grade 3 second instrument and that not being allowed, similar with no backup piece to play, not doing so well as hoped in the full piece etc etc. So it sounded quite tough on them. Though to be honest I have less sympathy if people don't read the rules of engagement correctly. Mill Hill and DAO were a much more positive experience !
