Collection: One-Row Melodeons

One-row melodeon, also known as a diatonic button accordion, is a small, lightweight free-reed instrument featuring a single row of ten melody buttons and typically two or four bass/chord buttons on the left side.

Unlike multi-row accordions, it is limited to playing in one specific major key (and its relative minor), making it simpler to learn but requiring specific playing techniques to navigate its unique push-pull note layout.
