Having just heard Elgar's cello concerto, again the cello is to me the sound of the soul. Yet there are others - and very different in tone and expression. The subcontinental raag form for instruments and /or voice  is so very different yet has the same effect on me. I have some understanding of the raag structure and what is going on in the improvisations but how different that is from the Elgar Cello sound.  Both are my music for the soul . 
Other cultures have other instruments to do the same  - and perhaps weird to us  and would that the ancients had sussed out recording stuff for us. 
Dance drama blends very well with some forms - I once devised a dance drama for young people to rather wistful piece of Japanese music. A bit of a liberty as I have no idea about it apart from feeling at one with its mood. Such music is a privilege of even having  lived, I guess
