A personal choice of music, live or recorded, can enrich a funeral ceremony immeasurably.
Arranging to play recorded music in a crematorium is almost always straightforward: the integrated sound system can be programmed before the ceremony to play a track or tracks of your choice at the press of a button.
On the other hand, you might consider hiring a musician to play or sing live music at the ceremony. If the idea of live classical music appeals to you, then I would be able to help you find a performer for the occasion.
I myself am a classically-trained concert pianist. If there is a piano or keyboard available at your venue of choice, then I would be happy to provide live music as part of your ceremony.
