Since many chimes are capable of playing in only a few keys, the original tune must be transposed to fit the chime. Also a chime may be missing semitones needed to accurately play the original melody. A decision has to be made to attempt it with changes to the melody, or that it will not be available on less than a given scope of instrument.
Chime Master libraries are always assembled with appropriate arrangement for the scope of the bells we are automating
as well as with respect to the tradition of the venue.
