Support the creation of Piano, Cello, Violin and Viola teaching videos on YouTube.
There are study videos of Bach Cello Suite No. 1 in G Major and how to play videos for piano pieces like the Entertainer. Example videos of tunes in piano method books and string methods are popular.
Currently I'm working on a series of videos using all 12 keys for violin, viola, cello and piano and creating a series of rounds for strings and piano solos.
