About ten years ago a well restored Triola appeared at a MBSGB
meeting and for the next few years the market price doubled. Once all
interested parties had been satisfied, the price dropped once more.

to play effectively, as it requires a musical input by the left hand,
in addition to turning the handle with the right. It is, however,
well worth having one properly restored and taking the time to learn
to play it. A well-played Triola will always get a round of applause.
Second-hand Triola rolls may be bought through mechanical music
society sales and specialist auctions (only very occasionally).
You may be able to obtain some modern rolls from Harald Mueller
