When a concertina is tuned or spot tuned it usually means that the instrument is tuned to itself. In other words it is balanced to the pitch that it was originally. If a concertina is repitched, the basic pitch is changed. Usually to A=440, the standard pitch in this country. When a concertina is repitched, every one of the reeds has to have its pitch changed. This is a lot of work considering a quadruple reed concertina has 374 reeds. A triple reed concertina has 318 reeds and a double has 204 reeds. Usually high pitched triples and doubles are harder to tune. This is the reason that having a concertina repitched can be an expensive but worthwhile undertaking. If the concertina player always plays alone, repitching isn't too important. If the concertina player plays in a band or with other concertina players, pitch is very important.
