It is helping me develop an innate sense of musicality. Spending time with the note, triad and chord relationships is a way of developing a felt relationship with music. It’s really enjoyable and is really opening up my abilities to improvise, create, and play music in ways never available to me before. Highly recommend. ### 5/5 — Fun ear training app! *2026-08-14* Highly recommend.
