This exercise is a little different than the the ones in the last set I uploaded and I’ve found it especially useful. Each track plays a cadence (in C Major) and then a robotic voice says the name of an interval. You have a few seconds to guess the note before the answer plays. If you haven’t done this before, it’s probably going to be very difficult at first. It certainly was for me. But it’s a lot of fun when you get the hang of it and it really helps your ear. Most notably I’ve notice my ability to prehear notes when I’m singing has improved. I included all intervals including accidentals, which makes this exercise very challenging. Maybe too challenging for someone just starting out. Unfortunately I don’t have a version with just the major intervals. I would recommend that if you’re getting frustrated, find a couple of tracks with simple intervals. Say Perfect 4th and Perfect 5th and work on only those for a while before building up. Good luck!
