Hi ,
of late I’m actually spending more time on my piano than I am on my sx.

I still find it easier to learn a tune for keyboard vs piano , though.

Figure piano will also help with keyboard skills, not so much with left hand,
for piano I prefer left hand arpeggio style songs, whereas keyboard I play full chords.

If I could sing it would be great, unfortunately never gonna happen , haha.

Part of the online piano course I found, one of the offshoots of the main course
500 songs in 5 days.
Teaches one to play a chord progression that could be used for 500 songs.
They include the chord chart and lyrics to go with them.

Over the 5 lessons one per day, they teach you how to improve and add the twiddly bits to spice up the chords.

Last day they even teach you how to add melody.

All done by ear which is something I’ve never been able to do.

Just the chords and lyrics.

Quite interesting really, just wish I could sing. Haha
