A minor third, a perfect fifth, an octave... These are names of intervals and are distinct from each other by the number of semitones between the two pitches. Recognizing some of the intervals in your repertoire can be a great tool in your cellistic toolbox.

Here you can download my sheet with suggestions for how you can explore the intervals with your cello.

(the very first interval on that page is played with D as an open string, and the E-flat with the second finger in the 4th position. The rest of the intervals are easier!)
