Song-Lego

Build a song’s form from Lego bricks while it plays. Every brick is one bar, every colour one part of the song. Then practise: slower, in a loop, with a count-in.

HOW IT WORKS

1Pick a song

Paste a YouTube link – the video plays right here. Or load your own file. Spotify, Apple Music & co. open next to it, and our clock runs along.

2Tempo

With your own file the program finds the tempo itself. With YouTube: tap 8 times on the beat, like clapping along.

3Build along

Press ▶︎. When a new part starts, tap its colour – or drag the brick to the right spot with your finger. Every full bar drops a brick.

4Check & PDF

Tap a block to change it. Identical parts in a row become 𝄆 2× 𝄇. Then a PDF for your teacher.

5Practise

Tap a block → Loop. Slow it down, switch on the count-in. With your own file also: more bass, less vocals, drums up front.

An invented song builds itself – then you know how it works.

Tempo – BPM
No song yet. Paste a link or load a file – or just press ▶︎ and count along.
SoundHear exactly the part you play.

An equalizer makes instruments louder or quieter, but it cannot cut them out cleanly. “Drums only” needs separate tracks – load them together (e.g. drums.mp3, bass.mp3, vocals.mp3), then you can mute or solo each one.

🔒 Sound only works with your own fileYouTube does not share its audio – that is YouTube’s rule, not a bug. Slow-down and loop still work. For Bass +, Less vocals & co. load a file (mp3, m4a, wav).
