Music 2Not a question this time, but I thought I’d share a
link to a Russian textbook I’ve used in class for both melodic dictation and sight singing. It starts really easy (and in C major), and then moves to A minor/different key signatures and harder exercises. There’s 1000 exercises, so I found it really helpful going through some for either sight singing (next to a piano), or melodic dictation (mainly in class). It’s in 10 different parts online, so if you want to look over the whole book, you’ll need to download all 10 parts. I didn't do music 2, so I'm too sure what range to focus on, but at uni we were mainly working up to around 250 (obviously just skip the ones that are out of your range).
Hope this helps!!
