I’ve been playing the mandolin for a few weeks now and have noticed that my left index to knuckle joint hurts after playing individual/8th notes for a few minutes. It seems that I tend to anchor there a lot as I also do on the guitar when I do breaks, but without the pain (maybe because my guitars tend to have C (baseball bat) to D shaped necks). It also doesn’t hurt when I play open and chop chords.
Is this normal and therefore I should continue on or should I change how I anchor for individual notes? My whole arm forms a near 90 degree angle with the left hand slightly twisted inward since the mandolin neck is raised a bit. The mandolin also has a V shaped neck so trying to push from the back of the neck is quite impossible for me and pushing down the neck and anchoring using my thumb doesn’t generate enough force for individual notes as much as it does chop chords.
Thanks!
