When I haven’t played in a couple of days, I have been suggested to try the following routine (and what I did last night)
* Scales in first position – just to get re-grounded. Re-establish first position
* Scales using the standard fingerings with all the shifts – C major and D major
* Some pieces I had worked on before
Then,new stuff. What do you do when you’ve returned to the cello after a couple of days without?
