I have 2 questions that came to mind after watching this upcoming Jazz track.
The vocals are tracked as a saxophone part with notes in place of lyrics, and the lead guitar part is tracked as a piano. A track like this that deviates from the traditional instrument roles opens up whole new avenues to explore and I'm not sure that HMX is 100% prepared for what people come up with.
My first question is can someone submit slightly different versions of the same track? For instance, could this song (or any other song that substitutes notes for lyrics) be available transposed into a bunch of different keys to accommodate people playing it on different instruments? Having to transpose the notes (or even attempt to play it by ear if you have perfect pitch) is not something most of us are capable of. Is there a limit to how many versions of a song can be submitted? It doesn't even have to create much more work either if once the original version is approved, different versions could be granted fast track status and not require as rigorous a review.
Also, when the author substitutes something like a piano for the guitar part, it can make more sense for the entire song be charted as a solo. Like a piano, the notes would just be finger tapped and not awkwardly played like a guitar. Is there some rule that states what the maximum solo length is? The only thing in the official rules about this is "...and use it only when there is an obvious solo." The case could easily be made for a song like this that the entire song is a piano solo.
