MemberBonjour, More often than not no key signature information is included when loopers up load a track, Most of us can work out by ear or some clever App on a phone what key the piece is in and work out the chord progression. BUT if you play a non-chromatic instruments, such as Harps, some flutes , some percussion instruments for example, it makes it really difficult to search the back catalogue here on Wikiloops to find a track in a suitable key for your instrument. Can we add the key signature when uploading please. Many thanks.
