A pine board, a few metres of drain pipe, a handful of bobby pins. Each one is an instrument waiting for the right saw cut. Pitch Forge works out that cut for you.
Try the forge below| # | Note | Pitch | Cut length |
|---|
Pick a xylophone, slap pipes, hairpin kalimba or pan flute. Set key, scale and your board thickness or pipe width, and every piece gets a length. Strike a bar in the middle and it rings full; near the edge it turns dull, just like real wood.
The blueprint draws itself: every length, where each bar rests, how to fit all pieces onto as few boards as possible, and a hardware store shopping list. Tick each piece off as it leaves the saw.
Type in what you actually cut. Hear it beside the target, see how far off it is, and get one plain instruction: trim this much, slide the tine under the bridge, move the plug down.
Record a riff and replay it on any build in your workshop, even one that is still a pile of offcuts.
🪚 We are a small crew of makers, music teachers and tinkering parents who kept asking the same thing at the workbench: how long should this piece be? Pitch Forge is our answer, built for people with a saw and a free Saturday.
🎶 Our mission is simple: make music-making as hands-on as it was before screens. Anyone should be able to turn scrap wood, pipe and hairpins into something that plays in tune.
📐 The app gives you exact lengths, a self-drawing blueprint, a cutting plan and shopping list, a tuning guide that tells you what to trim, and an on-screen instrument that sounds like the one on your bench.
Cut once, tune twice, play forever.
