I love this website. The owner Paul Gardner has made accompaniments to much of the standard student repertoire for violin. The list is quite extensive and his playing is wonderful. Not midi!!

This is an amazing service. All of my private students are now subscribers. Runs on Windows, Mac, and mobile devices. It features many student pieces, scales, drones, etudes, as well as concertos, sonatas, etc.

Youtube channel with piano accompaniments.

Steven Maloney now has accompaniments for all the Suzuki pieces. Like on the general Accompany site you can slow down the accompaniment or loop sections.

This company makes books and practice CDs for scales and violin literature. The Cds feature slower practice tempos and real orchestral back up tracks.

Most other Suzuki volumes are also available with an accompanying CD.

Large repository of backup tracks for fiddle tunes.

In the "Sheet Music" section you will find the PDF files for these songs (under "Christmas Carols").
