This is the first step in creating an app that includes both jazz trombone chords and a metronome tool. Currently, there are tracks for 35 (mostly) jazz chords and a trombone drone available in the key of Bb, each 12 minutes in length. A metronome tool has also been embedded near the chord tracks for your convenience. If the demand is high enough, I will finish developing the full app soon. The completed app would include a logical layout, chord symbols, organized categories, a user-friendly interface, and basic accessibility features. Please share your thoughts and feedback!
