A Spanish pianist is on trial and could face more than seven years in jail after a neighbour accused her of causing psychological damage and noise pollution.

The plaintiff, identified only as Sonia B because of tribunal regulations, claims she suffered from noise contamination between 2003 and 2007 owing to the eight-hour practice sessions, five days a week, of Laia Martin, who lived below her in a building in the north-eastern town of Puigcerdà.

Martin, 27, now a concert pianist, denies she played at home that often, saying she took regular classes in other towns.

El País newspaper reported that Sonia B told the court on Monday that she had eventually moved house, and now hated pianos.

The trial continued on Tuesday and is due to end on Friday.
