Other Accompaniment Websites
While I don't offer piano accompaniments for vocal music on my website, I can recommend the following websites for such tracks:
www.mp3accompanist.com - this is an excellent place to find accompaniments for classical songs and opera arias
www.pianotracksformusicals.com - for Musical Theatre and Showtune accompaniments try this comprehensive website
If you are looking for chamber works (trios or larger), or works not on my site, try this new website:
www.chambersound.com - an attractive website with an expanding range of chamber works plus some lesser known duos.
