I really like the layout and the ease with which I can practice on the go. This is exactly what I was looking for to help stretch my ears and my skills, and to have it laid out in an easy-to-follow format at such a reasonable price is incredibly useful.
One of the things that sets this method apart from others I’ve tried is the ingrain section of each lesson. I have found that most other ear training courses encourage immediately singing and differentiating intervals or chords without giving ample time for the sound itself to permeate the inner ear and the mind. Being able to do them “on-the-go” is invaluable, as there are so many demands in the modern world that being able to practice during time that would otherwise be “wasted” allows me to keep moving forward even during my busiest times.
I also enjoy the pace of the singing tracks. Even in busy environments such as a bus or a train I am able to practice hearing the intervals in my inner ear. I am hearing the music in my mind more clearly now than I ever have before. I also find the checkpoints incredibly useful. I am able to use them as a quick assessment of how instinctual my listening has become.
I am trying to turn my ear into a reflex understanding of music, and having these tracks allows me to determine whether I am guessing, thinking, or hearing.
