What Kinetic Melody: Pendulum is for

Kinetic Melody: Pendulum is a music app built around watching sound. Each ball swings on its own pendulum path, and whenever a ball crosses the line it plays a note. Over time those notes settle into rhythms and melodies that you can see as glowing waves, spirals, orbits and other shapes.

The developer describes it as a visual music maker for hypnotic rhythms, patterns, songs and short videos. It suits people who like building loops from scratch, people who prefer to start from a preset and tweak it, and people who simply want to watch familiar tunes played out as motion. The developer lists 11 interface languages, among them French, Chinese, Russian, Tagalog and Afrikaans, so the controls can be read in any of those.

Building a composition from balls and tempo

A composition starts with the number of balls. You choose how many there are, then set a starting tempo in BPM. Tempo Delta is the setting that separates the balls: it gives each one a different speed, so the pattern drifts apart and comes back together in ways a single tempo would not produce.

Pitch is set by a root key and a musical scale. You pick the key, then the scale that sits under it, and every note the balls play comes from that choice. Sound, colour and motion are all adjusted in real time, so changes to the tempo or scale are heard and seen while the pattern is running.

Instruments and visual styles

The app offers 19 instruments. The developer names piano, music box, kalimba, harp, guitar, flute, marimba, koto, sitar, synth and tabla among them. Each one changes the timbre of the same pendulum pattern, which makes it easy to hear how much of a rhythm comes from the notes and how much from the spacing.

Visual styles control how the balls move on screen. The listed styles are Pendulum, Wave, Orbit, Infinity, Spiral, Flower, Heart, Star, Disc and Bounding. Some advanced visual styles and some scales require a PRO upgrade. The rest are available without it, and the developer does not describe a subscription.

Starting from templates and learning the controls

Templates are ready-made compositions, grouped into Classic, Groove, Hypnotic, Relax and Shapes. They are a quick way in for someone who does not want to set ball counts and scales from nothing, and they can be opened and then changed like any other piece.

A built-in tutorial covers the core vocabulary: balls, tempo, Tempo Delta, root keys, scales, instruments, colours, saving and full-screen playback. The tutorial is the closest thing the app has to a guided first session, and it is aimed at the terms that appear throughout the rest of the controls.

Playing familiar melodies with moving visuals

The app also plays known melodies through animated patterns. The melody runs while you watch, and you can change the instrument, shape, speed, colour and lane display during playback. This lets you hear the same tune on a harp, then on a kalimba, without stopping it.

When a run finishes, you can replay it whenever you like. Changes made during one playback carry into the next, so a version you have shaped can be heard again as it was.

Saving, exporting and sharing your pieces

Creations you want to keep go into a collection called My Pendulums. From there you can rename a saved preset, delete it, or choose which thumbnail represents it, which helps when a library grows over time.

Finished pieces can be exported as audio or as video. You select the export format and the duration before rendering, then save the result to your device or share it with friends directly from the app.
