DragonScales 3-Octave Scales and Arpeggios for Cello: In Slow to Fast Rhythms, in All Keys, Includes Audio Play-Alongs

My scales has vastly improved. I like the playalong feature. Good book to have in my music library.

Very comprehensive practice but I would not recommend it for a self teaching beginner. I gave four stars because I think it would be great for intermediate cellists.

I've never seen a method book that focuses on scales and arpeggios with such a clever play-along system built into the book in the form of QR code links. Now i can practice my intonation and rhythm with the reference audios (from youtube) anywhere i go. The book is hefty though, at 246 pages. There is a PDF version available from the authors website, however. You still need a phone to scan the qr-codes in the PDF to access the audio. Overall, great product.
