Bellowsby is a little red accordion with pearl buttons, a nickel grille and real bellows to pump.
On iPhone Duo, open the phone and hold it like an accordion, one half in each hand, then close it a little and open it again. Squeeze gently for a soft note, faster for a full, bright one. On any other iPhone, hold it sideways and squeeze the bellows with two thumbs.
Pick a nursery tune and every squeeze plays the next note, or switch to Manual and make up your own. Every note is made as you play, from accordion reeds modelled in the app.
No ads, no in-app purchases, no accounts, and nothing collected.
