A spoken name already has timing, emphasis, and pauses. Using your own name or an invented phrase, you can turn those features into a short rhythm without needing to write a melody.
Begin with ordinary speech
Say the phrase naturally at a comfortable volume. Tap once for each syllable, then notice whether some taps feel closer together or more emphasised. Do not force every syllable into the same duration just to make the pattern look tidy.
Repeat the taps without speaking. If the rhythm no longer reminds you of the phrase, return to the spoken version and choose one feature to preserve, such as the longer final syllable.
Give the pattern a second setting
Place the rhythm over a steady, slow pulse made with your foot or another quiet sound. Explore where it starts relative to that pulse. Starting later can change the feeling without changing the order of the taps.
Use invented words when playing with someone else so nobody feels that their name or accent is being mocked. The exercise is about hearing speech as timing. Finish by speaking the phrase again and noticing which details the tapping kept and which details, such as pitch or tone of voice, it left out.
