Ukulele

Triangle.

Rhythm egg

if you're a singer, then you can learn a couple of chords on guitar or piano and just bang them in a loop and sing on top. It doesn't take a lot of practice to be able to strum a guitar and sing at the same time.

Neither does a piano

You just play the chords with your left hand and play the bass with the right hand

Start with the bass, then play the chord

dum-Tam dum-Tam Tam dum-Tam dum-Tam Tam and so on
(bass-chord-bass-chord-bass-chord)

Singing and playing this at the same time is pretty easy

After that you'll find that you sometimes make mistakes in the rhythm or with the notes, and you'll try to incorporate those mistakes into your playing

And then you're on your way to become McCartney


That shape is a marvelous shape

singing. Everyone does it and it's always available

the guy's problem is that he sings and he would like to accompany himself with another instrument

Your organ.

Along with the other joke answers, the tambourine isn't very demanding. I still remember watching this performance on tv, and the verdict of me and my siblings: "That guy isn't doing much!"



Even today, when I know that they were all miming, he still has the awkward appearance of a guy with nothing to do trying to look busy. I wonder which Moody he is: Ray Thomas?

Healing music is a also not easy to learn. In general, music from signing bowls is the most difficult instrument to learn, especially if you are not already experienced with playing on other stringed instruments.
