LET'S START STRUM !!!

Now we play the three chords adding the G chord to close the rhythm which will be 4/4. Let's play each chord once.

We still play the ukelele strings from top to bottom.

Let's now play the same chord twice and then move on to the next one. We will then play the chords:
G G C7 C7 D7 D7 G G.

Let's now play the same chord sequence by playing the same chord four times.
G G G G C7 C7 C7 C7 D7 D7 D7 D7 G G G G

We play the same chords again, always 4 times, but playing the strings once from top to bottom and the next from bottom to top. Our first, simple strum that will begin to shape our sound.
