First, learn how to play the chords. You could download the keyboard chord chart from this post and start practice playing them. I would suggest you start out with learning these chords first – Dm F Gm Am C Bb – When you learn these five chords you could play just about all Lao country songs out there because with the keyboard you could use the transpose button for scaling the notes.
Second, learn the melody. For me I used a program call Vanbaso. I just load in the midi file of a song that I want to learn. Mute all the channels except for the melody and a play along with it. And if I want to get the chords for the song I would mute all the channels except for the guitar chord. You could also lower the tempo if it is too fast for you. Pretty cool program to get the chord and the melody part.
If you are not a visual person then I would suggest this program Midi2Notation. Just get the player version it is free! With this program you could print out the melody part of a song or just the guitar chord. Check it out!
The key here is to learn the chord of a song, the melody and then bringing them together. Have fun!
Download these programs, a free midi and test them out. This is how I learn! If you like to share with us how you learn your keyboard lessons please post it here.
