1.1.5.3 Enharmonic Intervals and Chords
Figure 1.34
Chords (Chords, p. 80) and intervals (Section 4.5) also can have enharmonic spellings. Again, it is important
to name a chord or interval as it has been spelled, in order to understand how it ts into the rest of the
music. A C sharp major chord means something dierent in the key of D than a D at major chord does.
And an interval of a diminished fourth means something dierent than an interval of a major third, even
though they would be played using the same keys on a piano. (For practice naming intervals, see Interval
(Section 4.5). For practice naming chords, see Naming Triads (Section 5.2) and Beyond Triads (Section 5.4).
For an introduction to how chords function in a harmony, see Beginning Harmonic Analysis (Section 5.5).)
