Did the Saint compose ciTTasvarams for his compositions, or did one of his disciples do that (I have heard a few sung with c.svarams by some schools)? Is there a provenance to these svarams?
chittaswarams for compositions such as nenarunchi (malavi), vara raga laya (chenchukamboji) and sobillu (jaganmohini) seem to be recent interpolations - not quite sure who composed them though.
Didn't we have this discussion some time ago? or may be in sangeetham.com. The chittasvarams sung for many tyAgarAja kRtis were attributed to GNB's father, G Narayanaswami Iyer (sItammA mAyammA, nenarunchinAnu, niravati sukhadA, telisi rAma, etc)
even sudha ji's version of sAramegAni anyamArga vichAramEtikE has chittaswarams.. Also anAdhudanu gAnu in jingla has swarams... who could have composed them,...
