This is an 'Honor' accordion or melodeon. It belonged to Pat Brennan, an instrumental music facilitator teaching traditional Irish music in schools.A melodeon is different from other accordions because it has buttons rather than piano keys. This allows the player to 'trip' between notes giving it the kind of sound associated with traditional Irish songs. Pat grew up in Ireland after World War II and musical instruments were expensive because they had to be imported. He, together with his brother and sisters, saved the money they earned working on local farms to buy their first accordion between them. Pat was 11 years old and the accordion cost £8.00.
