Composing an original startup tune from scratch

Every guide on this site so far assumes you're converting an existing song. But there's a fourth option beyond Mario, Tetris and the Imperial March: write your own. A signature tune nobody else has, that says your quad is armed.

You need zero formal training. A startup tune is 5–15 notes. Here's a recipe.

Start with rhythm, not pitch

Tap it on the desk first. A good arm tune has a memorable rhythmic shape — think of how recognisable "shave and a haircut" is from rhythm alone. Three patterns that always work:

• Short-short-LONG. Two quick notes into a held one. Confident, final.
• Galloping triplet. Da-da-dum, da-da-dum. Energetic, good for freestyle rigs.
• Question and answer. A short phrase, a pause, a short phrase that "replies". Charming on a whoop.

Pick one, tap it until it feels natural, and only then worry about notes.

Pick five notes that can't go wrong

Here's the composer's cheat code: the major pentatonic scale. In C, that's c, d, e, g, a. Any sequence of these notes, in any order, sounds coherent — there are no wrong combinations. It's why every music teacher starts children on the black keys (which form a pentatonic scale).

So: take your rhythm, assign each tap a note from c5 d5 e5 g5 a5 c6, and you have a melody. Genuinely. That's the whole trick.

A few shaping tips:

• End on c (the root) for a "finished" feeling, or on d/g for an "alert, ready" feeling that suits an arm tone.
• Make the last note longer than the rest. A tune that ends on a short note sounds like it tripped.
• One leap beats many steps. A jump (say c5 to g5) followed by stepwise motion is more memorable than a wandering line.

Write it in RTTTL

A tune like this fits in one short line. Example — short-short-LONG, twice, answered:

mytune:d=8,o=5,b=140:c,e,4g,c,e,4a,g,e,4c

That's nine notes, well under the 128-byte budget, and plays in about three seconds. The RTTTL syntax guide covers what those prefixes mean; the common mistakes post covers why it might not play the first time.

Test it in the converter's preview before flashing — iterating in the browser beats iterating with a lipo and a screwdriver.

Refine on the bench

Melodies behave differently on motors than in a browser preview (here's why). After the first bench test, expect to:

• Shift the octave until it projects — 5 and 6 are the sweet spot.
• Slow it down. Fast passages smear on motors; tempo advice here. If in doubt, drop b= by 20.
• Cut a note or two. Every draft tune I've written got shorter between version 1 and the keeper.

Why bother?

Practical reasons: original tunes have no copyright questions, they're as short as you want, and at a busy meet your ear picks your tune out instantly — everyone else armed to Mario.

But honestly? It's the same reason people design their own quad badges. Five notes of your own beats fifty notes of someone else's. Write the tune, and when your mates ask "what song is that?" you get to say: mine.
