I am running a site for musicians and I need a Joomla [url removed, login to view] Module/Plugin/Component that can transpose the chords of a basic chart. I need a dropdown menu that allows the user to choose how many half-steps to go up or down.
Well the key to my survival
Was never in much doubt
The question was how I could keep sane
Trying to find a way out
This song is in Em but I'd like it in Dm, which is step flatter. With one click on that dropdown menu, Em should become Dm, C in Bb, D in C, B in A... you get the picture...
