A progressive system of scales for Cello in four levels by Orfilia Saiz Vega. French and English Language Version. We all agree that scales are a basis for learning cello technique, which is why we include scales in our teaching. The trick of course, is how to integrate scales into the learning process so that at the moment the repertoire demands the technique, the fingers are able to respond. All too often scales are divorced from their musical environment or teachers are compelled to cut and paste from traditional scale books to try to match technique and learning.
