arrow key music- and search

Hi it would be cool if we could for example click a note and then hit the right arrow key and the next note would play and if we hit the right key the previous note would play.

Also I agree with the other post that it would be useful to be able to add singing range parameters to the search so that we can narrow the songs e.g to pop music that doesn’t go higher than B5 or or to classical music with the lowest note being f5 or whatever.

Another thing is maybe turning on and off octave numbers while up down and “normal” C is useful for distinguishing it can also be useful to have actual numbers like c7 etc

Finally what ways are there to support this website because it’s awesome and must’ve taken a lot of work yet I son’t see any ads ^_^
