There is three things to learn and you will be playing in no time. It took me one summer to learn all the chords and to play them and now I am playing for concerts and church services.
Three things to learn:
Notes
Scales
Chords
On the white keys there are 7 notes to memorise, on the black keys there are 5 notes to memorise they just repeat. Once you learn your notes everything will be simple. Now to give you some warning not all of it is simple but it is easy!
The only hard thing in my opion is learning to lead your base, but only focus on one subject at a time.
