Something a few have chatted about in here, as well as hearing this lots during my time teaching, is people want to further their finger dexterity and get better technique. I hear this, I’ve had this issue myself over the years. I would always recommend finding an in-person teacher for this, but someone who gets what you are after.
As well as finding a teacher it’s worth making sure that the material that you work on when thinking about your technique is going to further your jazz playing. That’s why I put together this new section in the classroom dedicated to all of the warm ups and enclosure exercises that I use on a daily basis.
They sort of follow this recipe: Enclosure or chromatic idea + Scale + Arpeggio.
To get access to a new one of these every week, sign up to one of the paid tiers of membership here. You will get a video of me playing the exercise, the enclosure that it contains and a transcription of both of these.
The video here is a short sample of one of these, in the classroom you will get the sheet music plus the recording in a few different keys too.
