Triad Brain Teasers 1. Do all triads contain three notes? 2. A Triad can be simplified to a stack of __?___( name interval ). Name all the intervals a triad can contain. 4. In this triad, is the bottom note the bass tone? 3. Is any three-tone combination constructed of thirds a triad? Give a counter-example/exception if there is one. 5. Give the formulas for constructing the four types of triads: & ?

1.Arrange as a stack of thirds in closed; root position (use shortcuts): eliminate doublings, memorize 7 triad letter names, spot 5ths, 4ths 2. Name Triad by its Root 3. Calculate the quality of thirds, which, in turn, gives triad quality 4. Determine if original is in root position or inversion (bass tone). Naming Triads Give triad name, quality, root pos. or inversion.

Inversions of Triads 1. Triad inversion depends only on the bass tone or lowest note. 2. Triads retain their qualities (M, m, o, + ) under inversion. Root in Bass =Root Position 3 rd in Bass =1 st Inversion 5 th in Bass =2 nd Inversion

Triads on Various Scale Degrees I.General Memorize the Pattern for Major II.Majors I, IV, and V are Major Chords ( modal scale degrees ). II, III, and VI are minor. VII = dim III.Minors Nearly all common harmonies use 6 and 7(LT)* * exception: III in minor normally uses f7 (subtonic) Why? M m m M M m o M I II III IV V VI VII I
