Singing intervals: something is missing?

[antoniomaiuri]

Way the first, therd,sixth seventh minor interval in the interval singing activity are only descending and the second therd sixth and seven major are only ascending? maybe something is missing. And the tritone?

The Interval Singing workshop focuses on diatonic intervals in the key of C. It will be expanded in the future. If you need to train to sing all intervals, you can very easily set up a customized exercise including all intervals.
