If you created the music in another way, let's say you just played it on the piano and recorded it, it may be unclear what your 'source' is. Commonly a musical score would be accepted, or if you completely improvised it may be accepted without any source at all. Generally many programs can export the musical score or provide a midi format. This makes it easier for others to work on what you created. If you're unclear what your source is, ask yourself "What would I use if I wanted to modify it?", the answer is likely to be accepted as source.
