The are several really fine piano transcription sites out there, and you should generally check my homepage for my latest transcriptions posts.  However if you’re new, here’s a list to kick you off:

• Firstly, check out all the posts tagged ‘Piano‘.
• I’ve posted alot of Bill Evans and Keith Jarrett transcriptions, so check each of those tags for some really good stuff.
• Pianologist is a great site with not just transcriptions but some really top notch analysis of reharmonisations etc.
• Olivier Bruchez’s Keith Jarrett transcriptions – this site is one I’ve visited many times over the years. Some splendid transcriptions of Jarrett’s solo and trio stuff, including many by Friedrich Grossnick, who is a bit of a legend when it comes to transcribing Jarrett. Includes several (immaculately done, may I add) transcriptions from the Carnegie Hall concert and The Melody At Night With You in PDF format.
• Bert Ligon’s trasncriptions should also not go un-noticed. At his University of South Carolina base, his nice list of transcriptions covers Keith Jarrett, Bill Evans but stuff for other instruments too…
• Colin Cambell’s Transcriptions – not just piano, but includes transcriptions of Chick Corea and Ellis Marsalis, amongst others. Nice site too.
• Continuum Transcriptions – snazzy Flash-presented range, including Bills Evans, Keith Jarrett. Look to bottom left of main content area to ‘zoom in’ in order to print them off or save them to hard-disc.
• Letter from Evans (on www.scribd.com) – not really ‘just’ transcriptions, more a whole welter of information which will make for fascinating reading for Bill Evans fans. Incredible that these are available on the net for free – there’s over 200 published pages here about Bill’s playing, compositions and musicians who he had played with.
• Lucas Pickford – anyone searching for piano transcription on the net would have almost certainly come across Luke’s impressive list. Includes word of Chick Corea, Herbie Hancock and Keith Jarrett.
• Charles Schneider maintains this site for EJMA it’s a veritable Gold-Mine of Transcriptions from a massive number of artists.
• Armand Reynault have made some very fine transcriptions on his site : it is a fairly short, but good selection, including Michel Petrucciani and Brad Mehldau.
• Bill Evans fans will wish to see this post, which has links to some cracking resources on Scribd.
• John Groves has a really nice site, with some good piano transcriptions.

Although not transcriptions there are some really good online learning sites out there now:

• Probably the best is www.jazzpianoonline.com which although not free has professional level resources and truly renowed contributors.
• Additionally Scott Raney runs his Learn Jazz Piano site, and also has a fine e-book.

Both of these resources are aimed at intermediate to advanced players, aimed to get your chops and sound right up there. You should be able to comfortably read music as well as be proficient in all keys and with a basic jazz approach already under your belt.

There’s a really good play-along i’ve recently bought that beginners/intermediates will find absolutely brilliant. It was unavailable in the UK, but I got it from sheetmusicplus here. It contains whole transcribed piano parts from a professional pianist, and TWO CD’s (one with the pianist, one without). Even for advanced players, it’s great to play along with the ensamble. Definately one-step up from the Aebersold playalongs, anyway.
