Klengel, Julius - Technical Studies for Violoncello, Volume 1 - Cello solo - G Schirmer Edition

Decent book of scale studies

I'm reasonably happy with Klengel's Technical Studies. I actually bought a copy for myself first and then decided to transition my students to this book instead of what we've been using. It is versatile because it starts with 2 octave scales and bowing variations for these scales, gradually increasing in speed (from whole notes to 16th notes). It includes arpeggios in 2 octaves with bowing variations and scales in broken thirds. Then, it provides all of this for 3 octave scales and for 4 octave scales. It's nowhere near as comprehensive as Flesch's or Fischer's books for violin, but it's a good place to start.
