The deadline for the 2023 Group Christmas Project submissions has now been extended to Monday the 11th of December.
I think special effects on the CELLO (and Viola) are SO COOL!
Whether left hand or extended bowing techniques, the Cello seems to be the most versatile string instrument (especially 5-string cellos).
Anyway, found the 'moderncellist' YT site - full of fun exercise & tutorial videos for special sound & bowing techniques on CELLO!
...and I know there are other similar sites out there to explore!
