The Johann Sebastian Bach Air on the G String
Bach's third Orchestral Suite in D major, composed in the first half of the 18th century, has an "Air" as second movement, following its French overture opening movement.
Has always been my favorite composition I have ever heard, both harmony and melodic moves I consider to be sublime to perfection.
I have seen Bobby McFerrin perform his version of it and inspired by the great vocal master, decide to create my own version with a guitar.
This piece is added as a bonus track to the 'Cooshi' album, just because I'm proud of it.
