Lessons ยท Unit 12: Intervals by shape
Intervals in bass clef
Interval shapes do not depend on the clef: a third is "line to line" in bass clef exactly as it is in treble. The only thing that changes is the names of the notes, and here you do not have to say them.
That is why this lesson goes quickly: it is pure visual recognition.
Drill
