I came across another fine online ear trainer, Good Ear. It includes a variety of ear training exercises, including hearing and identifying intervals, chords (ranging from simple triads all the way up into extended jazz chords with alterations), cadences, and scales. There are also different options you can use to fix the root of the exercises to always be the same pitch or change, play back in different sounds, and give you the correct answer or not for feedback. There is even a section that gives you random pitches to test your “perfect pitch” recall abilities.
There are plenty of exercises good for beginners, but I found some ones that kept me challenged too. I especially want to go back and do more of the jazz chords exercises. I have a habit of lumping chords with extensions (9ths, 11ths, 13ths) sonically with the basic 7th chord, which gave me some answers that were close, but wrong. Some chords with alterations are more challenging to identify and some chords are easy to mix up with others (e.g., an A7b9 sounds an awful lot like a C#dim7 because they contain 4 common tones).
It’s a good resource, check it out.
