At first, I liked it. The note recognition part was perfectly good. Then I clicked on the tones and intervals part. There was zero explanation for what CS, DS, and WT are. The app isn’t talking about dal segno either... I tried looking it up, but I still have absolutely no idea what they mean. Is it something to do with modes? Not sure if I’ll ever know 😂 If you’re gonna use abbreviations, you need to explain what they mean because it’s not common knowledge. The annoying part is, you can’t use the other sections (key signatures, triads, rhythm, etc) until you pass this section...
