Blue note c definition6/17/2023 The tritone has appeared in Western music for hundreds of years. The tritone in chords The Tritone’s Diabolical History In dominant chords based on whole tone/half tone scale between root and #11, b9 and fifth, #9 and 13, third and minor seventh (as described above).In half diminished chords between root and b5.In diminished chords between minor third and major sixth, 9 and b13, 4 and major seventh, b5 and root.In phrygian chords between b2 and fifth.In min6 between minor third and major sixth.If I go through all of the popular chords, I may find the tritone in the following places: To harmonically resolve this, the third moves up a half step to the tonic root and the seventh moves down a half step to the tonic third. The relation of third and minor seventh is a tritone. If we look at a dominant seventh chord we have the root, the major third, the fifth and the minor seventh. Of these, the dominant is the one which wants to resolve itself the most. The slash indicates two names for the same note depending on if the note is sharp or flat.įirst and foremost, the tritone is an important part of our harmonic system, which consists of three main functions: the tonic, dominant and subdominant. Can be split up in three whole steps and in two minor thirds.Lies right between the least hard sounding intervals the perfect fourth and the perfect fifth.Consists of two notes six half steps away from each other.One of the “hardest” sounding intervals we have.I prefer to give them a degree of hardness because it is a rather neutral and somewhat objective term. There are many words to describe the sounds produced by an interval dissonant, consonant, disturbing, eerie, and so on. The more they have in common, the “softer” they sound. Certain intervals have more harmonics in common than others. You’ll perhaps be able to best recognize this with church bells, where these notes are very easy to distinguish. Intervals sound different depending on the distance between the two pitches. The reason for this is because each pitch consists itself of many harmonics higher notes that resonate alongside the “main pitch”. Listen to the Tritone Interval In Isolation As a result, this places the tritone between the perfect fourth and the perfect fifth, making it a diminished fifth (with a flat) or an augmented fourth (with a sharp). So why does it include the prefix “ tri” meaning three of something when it consists of only two pitches? The “tri” actually refers to the three whole steps in between the two notes. The tritone is an interval, meaning two pitches sounding at the same time.
