Trinity College AP-20 Anglo Concertina with 20 keys
Trinity College AP-20 Concertina offers all the features and craftsmanship of the classic turn-of-the-century instruments at a moderate cost. This instrument is light weight, portable, easy to learn and fun to play. Trinity College Anglo Collection Concertina features a diatonic button system which works much as a harmonica does. Each button produces two different pitches, one on the blow, another on the draw. Though they can be played in other keys, they are most played in C or G. Harmony may be obtained by pushing more than one button at a time.
