This is a guided 30 minute technique warm-up routine, similar to what I would do in a group bass class. It starts out with some larger motions and long tones, moves on to focus on left and right hand challenges, and then finishes with long tones again. This specific warm-up is good for bassists who know their 2-octave scales, and have some experience with both legato and spiccato bowing.
*One tip for the scale portions: Particularly for play-along videos like this, I find it most helpful to join the scale after two notes, so you are playing in thirds with me. It's easier to hear yourself, and it also helps you learn to blend. This may get distracting when playing the rhythmic patterns later on in the video, but it's a good way to play the simpler scale exercises.
