Viola Time Runners is compatible with Fiddle Time Runners: all of the tunes (except the C string pieces) may be played together by viola and violin, either in unison, in unison with a few simple changes, or with the ensemble parts provided. The book uses the finger patterns 0-12-3-4 and 0-1-2-34, and includes 'C string specials'; extra pieces to give plenty of practice on the C string.
