Practising with Yamaha PSR-SX600 keyboard

I am an absolute beginner, 54 years old, never played an instrument before. This video was taken after I got a Yamaha PSR-SX600 keyboard about three weeks before. Just for fun, I played two synth tunes. Having a synthesizer was a dream for almost 40 years. I never bought one because I thought I am not talented to play it. This might be true - but with today&cheaper arranger keyboards I give it a try and live my dream. I might never be a good musician but I enjoy playing.
