Shalini: "if I sing some scales and practice the intervals in the song and others, before I sing, it is much easier"

I'd completely forgotten about doing practise like this - it's been so long since I did any other form of singing! So, I'll be doing the same as you from now on - regularly working with the scales and intervals! Fortunately for me, my range seems OK for the folk songs I sing - but when the interval is steep, it can sound like I'm scraping a blackboard (or trawling the sea bed) at times...
