Reddit reviews BF101 - The Complete Scale Compendium for Violin

I'm an adult learner and I started with Suzuki. I actually like it. I also use Whistler's Introducing the Positions Vol. 1 and my preferred scale book is The Complete Scale Compendium for Violin by Larry Clark although I also have Galamian's Contemporary Violin Technique. I like Larry Clark's because it's good for beginners and very thorough. Galamian's and Carl Flesch's Scale System are good if you're really familiar with scales and need something more advanced.

YouTube has a lot of excellent videos. I prefer Eddy Chen if I'm stuck with something really particular. His advice helped me to really develop a practice routine that helped me stay focused and actually accomplish something. If you do Suzuki, there are some instructors who do play along videos (some even do slower tempo versions) of the etudes which I find helpful.
