Help me to play bits of tunes on instruments or by using a tablet

Encourage me to play bits of music I have heard before as well as making some up

Stick a marker on ‘middle C’ on a keyboard and show me where it is
Show me, gently guiding my hand if necessary, how to play simple patterns of three or four notes next to each other that start on C
Encourage me to use one finger to start with, moving my whole hand along to get to the next key
In time, you can encourage me to use my thumb too, and then, one at a time, the other fingers as well – use either hand, if I have the capacity for fine motor control
With the help of a trained musician if necessary, show me how to play the jingles, ringtones and other bursts of melody that I hear around me
Try doing the same thing with touchscreen technology
