What are the instruments in Iridescent?

the sitar

It is Wind. That is my guess......

there is no such thing as a wind instrument, an air instrument, or a tapping instrument. there are woodwind instruments (including saxes, bassoons, oboes, English horns, clarinets, and flutes) brass...

Probably ... depends on user feedback. What may be a quality instrument in one persons eyes may be junk in another's, and vice versa. It's all personal preference.

The Pipe Organ.
