Boomwhacker colours
Hum a tune. The page turns it into colours, and the whole class plays it back on the tubes.
Hum me your song. I lay it out in colours on the tubes, and the class plays it back.Hum me a song!
The microphone turns on when you tap, listens for six seconds and turns off again. Nothing is recorded or sent.
How it works in class
A child hums a short tune into a phone or tablet, say the start of a song everyone knows. The page hears the notes, moves them into C major and shows them as a row of colours. Tap "Play it" and each colour lights up when its note is due. Whoever holds that colour plays it.
Handing out the tubes
Eight tubes, eight colours: C red, D orange, E yellow, F light green, G dark green, A purple, B pink, and the high C red again (the short tube). Give each colour to one child or a small group; anyone without a tube sings along. Tap a tube at the top of the page to hear it, so every child knows how theirs sounds before you start.
Reading the row
Read it left to right, like a sentence. Two of the same colour in a row means: play twice. Start on "Slow", then "Medium"; once everyone's got it, "Fast". "Show it big" fills the screen for the projector or whiteboard. There's nothing to print.
Why C major?
A set of Boomwhackers usually has just the eight notes from C to high C. Any tune you hum is in some key. The page finds it and moves the whole tune into C major: it sounds a little higher or lower than you hummed it, but it's the same tune, and every note fits a tube. A note that falls in between goes to the nearest colour.
For parents and teachers
The page only listens when someone taps, and only for six seconds. The tune is read in the browser and forgotten right away: no recording, no account, nothing is sent. There's no score and no comparing children. More about Brumm Kids and ideas for music lessons in primary school.
