Pick a photo and hear it as a whole song. Its colors pick the key, four strips across it play the drums, its brightest spots sing the hook, and how busy and colorful it is sets how hinged or unhinged it gets. Then Magic Blocks adds the bass, melody and song structure.
Your photo then swirls through the song's fractal art. Name the song, swap in your own music if you like, and make a video for TikTok or Reels.
No AI: your picture is never looked at for what's in it, only its colors and shapes, and it never leaves your device. See how ↓
Every song on RockBlocks can play as fractal art, drawn by fixed rules: the melody leaves sparkles whose angle around the center is the note's name and whose distance out is how high it is, the kick makes the picture breathe, and the more unhinged the song, the busier, more colorful and more lopsided the picture. PictureSong reads a picture by the same rules, the other way round.
Nothing looks at what's in your picture, only its colors and shapes, and it never leaves your device: it's read right in the browser into a short code, and the song is built from the code. That's all a share link carries. Try a screenshot of a song's own fractal art and you'll hear something related come back.
PictureSong and Magic Blocks don't use an AI model and weren'ttrained on anyone's music. Every song is built with the same tools you use on the rest of RockBlocks, one layer on top of the last.
The drums are the foundation
Everything starts with the beat. On the hinged end it's a groove written by hand for each style: rock, pop, funk, hip-hop, dance, shuffle. Turn the dial up and the grooves get rolled from rules instead, but they always stay something one drummer could actually play.
The bass line comes from the drums
The bass listens to the kick drum. Every kick gets a bass note, and the snare is its second anchor. The more unhinged the dial, the more the bass adds: passing notes between hits, walks up to the next beat, runs at the end of a bar. Every note is kept in the song's scale.
One hook runs through the song
Every song gets its own hook: one short tune built the way songwriters build them. It has a few notes, a rhythm with a kick to it, mostly steps with one leap, and an ending that asks a question the next phrase answers. The chorus sings it plainly. The verse keeps its rhythm under new notes, the pre-chorus climbs it, the bridge turns it upside down and the intro slows it down. It's written in steps of the scale, so it follows every key change, and where it meets a new chord it bends a step to fit. However unhinged the song gets, you can still hum it afterwards.
One part gets the spotlight
The chords come from music theory: each one is built from the scale on the bass note underneath it. Then one part, the drums, the bass or the melody, gets the spotlight: busy drums with sixteenth notes and ghost notes, a bass line that runs and sings, or a melody that decorates the hook. The other parts keep it simple and leave it room, so no two songs are crowded in the same way. Turn the dial up and the spotlight moves from section to section.
The surprises come from dice rolls inside those rules, not from a model guessing what music sounds like. That means every note can be explained, and every note can be changed: open the song in the editor and Stacks, or learn the same rules in BlockTheory.
PictureSong is a free picture-to-music converter built into RockBlocks: pick or take a photo and it becomes a whole song, then a music video of that photo. It reads the picture by fixed rules, the fractal art's own rules run backwards: the main color picks the key (colors around the wheel like notes around the octave, red as C; bright and warm is major, dark is minor, gray is pentatonic), the picture cut into four strips plays the drums (dark along a strip's bottom is the kick, edges through its middle the snare, bright detail along its top the hi-hats), the brightest spots sing the hook, and how busy, colorful, contrasty and lopsided it is sets how hinged or unhinged the song gets on a 1–100 dial. Magic Blocks then adds a bass line built from the drums, chords and a melody, and arranges it into one of the ten most popular pop song structures. It isn't AI: nothing looks at what's in the picture, only its colors and shapes, and the photo never leaves the device — it's read in the browser into a short code, and a share link carries only that code. The same picture always makes the same song. Afterwards the photo can be blended into the song's fractal art (Painted, Stencil, Ghost or Kaleidoscope, with the hook's spots lighting up as their notes play), the song renamed with emoji, and the music swapped for a song of your own (an MP3, M4A, WAV or OGG up to 25 MB and 8 minutes, played on the device and never uploaded) so the art pulses to its beats. Export it all as an MP4 for TikTok, Instagram Reels or YouTube Shorts, open the song in Stacks to edit every part, save it, or post it to Drummit. Free, no account needed.
