I didn’t watch the live lesson but i find it much easier for me to learn songs that have lyrics (i know).
At first i learn the motions and as soon as i got them memorized i sing (in my mind – singing loud seems quite a bit more complicated to me) and that makes it much more easy for me learing a song.
I believe while singing the song i dont need to be thinking about timing as much which is a much more foreign concept to me than singing.
