Starting singing lessons and also working on writing down the melodies of my songs

I started singing lessons last month, and my teacher has asked me to write down the melodies of the songs I have written since I wrote my first song in April 1986 (after the Chernobyl nuclear accident late that month, I wrote a punk song about it while running in the rain). The process has made me realize that I have actually not always been sure exactly what the melody is all the way through many of the songs, which hasn't made them any easier to sing well. Now that I'm pinning down my intentions, I can be more precise in singing my melodies, and varying them if I want to. (Andrew Shields, #111words, 10 February 2025)
