Review from cmuse.org 2021
“This is one of the famous series published on the topic of Double Bass instruments. Being highly informative and instrumental in learning the instrument. These books are priceless, highly pleasing, and with all-around evaluation, they come with great graphs and clear scales for the understanding of the conherecepts in an all-around simple manner. This is one of the great volumes from Keith Hartley.”
“Rapid service (arrived early). Well packed.”

I find the length of the pieces perfect -- just enough to teach a particular fingering, bowing or articulation. Plus, the fact that this is real music (Book 1) rather than dry exercises is fantastic for young students.
