In this lesson we are going to continue our study
of intervals, but include intervals with accidentals, compound intervals
and interval inversions.

Intervals
with accidentals
If you can determine the size and quality of natural
intervals, you can identify and write the more complex intervals
that use accidentals. You do this by relating them to their natural
spellings. Follow the line of reasoning slowly and carefully as
formulated in the next three rules. Although these may look like
simple concepts, this is an area where many students make mistakes.

on the printable PDF practice drills for this lesson.
Rule
1 If you raise or lower both notes
of an interval the same distance, the quality of the interval remains
the same.
Rule
2 If you (a) raise only the higher
note or (b) lower only the lower note, the interval increases in
size.
Rule
3 If you (a) lower only the higher
note or (b) raise only the lower note, the interval decreases in
size.
