Thanks John , got it.

3 months ago I wouldn’t have had a clue what you were talking about.

What amazed me also, the amount of songs that can be played with something as simple as 4 chords.

One of the paks as part of the course is 500 songs in 5 days.
She teaches the 4 chords, how they’re created so that the can be transposed. Each of the 5 days one learns new things. Basic rhythm, adding fill ins to trick them up, last day how to add melody, basically by ear..
All one gets is 500 songs , chords and lyrics. Not a single written note in sight.
Never thought I’d be able to do it, as I was so obsessed with reading notes.

Goes to show , never too old to learn. ( can teach an old dog new tricks ,haha)
