Of musical instruments few are suitable. The human voice is the best, and the only one which can be usefully employed in chorus. Anything like an orchestra implies infinite rehearsal, and introduces an atmosphere of artificiality. The organ is a worthy solo instrument, and is an orchestra in itself, while its tone and associations favour the religious idea.
The violin is the most useful of all, for its every mood expresses the hunger for the infinite, and yet it is so mobile that it has a greater emotional range than any of its competitors. Accompaniment must be dispensed with, unless a harpist be available.
The harmonium is a horrible instrument, if only because of its associations; and the piano is like unto it, although, if unseen and played by a Paderewski, it would serve. The trumpet and the bell are excellent, to startle, at the crisis of a ceremony.
Hot, drubbing, passionate, in a different class of ceremony, a class more intense and direct, but on the whole less exalted, the tom-tom stands alone. It combines well with the practice of mantra, and is the best accompaniment for any sacred dance.
