Intervalsgood definition of an interval is “the spacebetween two notes.” Figure 1-1 shows theintervals from the half step/minor second up
to the octave, all based on middle C. The mostcommonly used term is shown above each interval,along with any alternate terms.
The chart that follows shows all the intervals,both ascending and descending, as they occur intunes from the standard jazz repertoire. Unlessotherwise noted, the interval in question is the firsttwo melody notes of the song. Play each exampleand sing the interval. If you can sing an interval

Inverting intervalsne of the skills a pianist must have is theability to invert intervals quickly. When you
invert an interval, you take the bottom note anput it on top, or vice versa. A new intervalresults, and the rules for inverting intervalsare simple.
When you invert an interval:• major becomes minor• minor becomes major• perfect remains perfect• tritone remains tritone
and the old and new intervals add up to “nine.”
Look at figure 1-2. If you invert a major third,C with E on top, it becomes E with C on top, a minorsixth. Major becomes minor, and three plus six addup to nine. In figure 1-3, a minor secondinverts to a major seventh. Minor becomesmajor, and two plus seven add up to nine.Now look at figure 1-4. A perfect fourthbecomes a perfect fifth. Perfect remainsperfect, and four plus five add up to nine. Infigure 1-5, a tritone inverts to another tritone.Because a tritone is right in between a fourthand a fifth, you could say it is “four and ahalf,” and four and a half plus four anda half equal nine.
O
Practice singing the intervals, both ascending and descending. Sing the melody,or “head,” of standards, bebop, and other jazz tunes while listening to records.

TTriads
riads are formed by stacking one third on top ofanother. There are four possible combinations:
major third and minor third, minor third and majorthird, two minor thirds, and two major thirds. Amajor third with a minor third on top of it forms amajor triad. A minor third with a major third on topforms a minor triad. Two minor thirds make up adiminished triad. Two major thirds form anaugmented triad. All four triads are shown infigure 1-6.
Play figure 1-6 and listen to the effect eachtriad has. Be aware of your emotional response toeach triad. In program music (music for TV, movies,the theatre) harmony is used to enhance whateveremotional response a scene demands. A major triadsounds happy, strong, or triumphant. A minor triadmay sound sad, pensive, or tragic. A diminishedtriad suggests tension, agitation. An augmentedtriad has a floating quality, suggesting, among otherthings, Bambi emerging from the mist at dawn(seriously). Although these have become clichés,they still work, otherwise TV and movie composerswouldn’t continue to use them. These emotionalresponses apply to seventh chords as well, the nextchords you will learn about. It’s no accident that sadtunes such as Benny Golson’s “I RememberClifford,” John Lewis’ “Django,” and the Raye-DePaul standard “You Don’t Know What Love Is” arewritten in minor keys, or that Bix Beiderbeck’s “In AMist”30 uses augmented chords. As you play, youelicit an emotional response in your listener, yourfellow musicians, and yourself. Be aware of it.

Triads are often inverted. An inversion is achord with a note other than the root on the bottom.Figure 1-7 shows both a C major and a C minortriad in their three possible positions: root position,as the term implies, with the root on the bottom; firstinversion, with the third on the bottom; and secondinversion, with the fifth on the bottom.Figure 1-7
