THE TARTINI FIDDLE TRICK.
Granting any two sounds are drawn from two instruments at the same time, there will be heard a third sound, the more perceptible as the listener is near the middle of the distance between them.
If the two sounds are succeeding ones in the order of consonance, as, for instance, the octave and the twelfth, the double octave and the seventeenth major, &c., the sound resulting will be the octave of its principal.
THE DEMON VIOLIN.
Hang a fiddle behind a partition, and, on striking a note on a second instrument on the other side of the wall, the unseen one will sound in unison.

Andy Andy’s adventure with the trumpet will be remembered. Hardly less amusing experiments are practised in the orchestras of theatres, especially when a play has run its hundred nights and time hangs heavy.
