 So the most important way to practice musical intervals, both melodically and harmonically, singing in context, when you're practicing on your own on the piano, you could do it with chords, the major chord, the minor chord and the dominant seventh chord, which is a nice colorful chord and practice all our intervals with respect to these chords. For example, the major seconds. Also do them in a descending manner. And then maybe some minor seconds in the descending fashion, F minor. Minor, of course, has variations, natural, harmonic, Dorian and melodic, right? So hope you found the tip useful. Cheers.
