First let me say you are doing a great job.
I would love to use bsic tabs (chord written above lyrics)
But what I discovered is that many times while there is a C written,
it could be first or second, up or down inversion wich really don't
sound the same at all. Maybe i miss something, but forgive me I knew to piano.
What I do is put up or down arrow(s) after the letter. But to do that i need to check the real piano sheet. But if everyone were doing so, it would make it so easy and precise.
Thanks for reading me.
