The Scarlatti SC-20 is an entry-level, 20-key Anglo concertina pitched in the traditional keys of G and C. Designed specifically with beginners in mind, it features a diatonic system—meaning it plays different notes depending on whether the bellows are being pushed or pulled—making it ideal for traditional Irish, English, and folk music. It is constructed with lightweight wood-end plates, traditional red bellows, and responsive plastic buttons, providing a comfortable, manageable feel for student players. The SC-20 is highly regarded as an affordable, user-friendly instrument that allows aspiring folk musicians to master basic fingering techniques and bellows control without the premium price tag of a professional model.
