Help me make sound patterns by varying a repeated movement

For example, by tapping more loudly or quietly, or faster or more slowly

Help me to make the connection between gradually hitting soundmakers with more force and making louder sounds as a result
Show me how to do it by placing my hand over yours while you make a series of bigger movements to hit a drum or tambourine
Fade your support, bit by bit, if you can
Now do the same, but getting faster or slower
You could try doing the same thing with my bare feet on a drum
Next, try helping me to play a small keyboard, pressing the notes, one by one, with one or two of my fingers, going from left to right to make higher sounds, going up a scale (like C, D, E, F, G)
Use the weight of my hand to push the notes down, supporting my hand from underneath
