Question: Why Do Tritone Substitutions Work?

How do you substitute chords?

The easiest kind of substitution is to swap a major chord with its relative minor, or a minor chord with its relative major.

These pairs of chords are, as the names suggest, related: they have two of their three notes in common..

Why is the tritone called the Devil’s Interval?

For centuries, it was called the devil’s interval — or, in Latin, diabolus in musica. In music theory, it’s called the “tritone” because it’s made of three whole steps. “The reason it’s unsettling is that it’s ambiguous, unresolved,” says Gerald Moshell, Professor of Music at Trinity College in Hartford, Conn.

How do you find a tritone?

If I go through all of the popular chords, I may find the tritone in the following places:In min6 between minor third and major sixth.In phrygian chords between b2 and fifth.In diminished chords between minor third and major sixth, 9 and b13, 4 and major seventh, b5 and root.More items…•

What is a tritone chord?

A tritone is the distance between the root and the #4. So, C to F# is a tritone. Years ago you could get banned from the church for even playing a tritone due to its very “harsh” or dissonant sound. It used to be called the “devil’s interval”. Ironically, the tritone is the key ingredient in a Dominant 7th chord.

What is a augmented 4th?

augmented fourth (plural augmented fourths) (music) A type of tritone in musical composition comprising six semitones. It spans four diatonic scale degrees like a perfect fourth but with an extension of a semitone. The number of diatonic degrees it spans is what distinguishes it from a diminished fifth.

Is a tritone the same as an augmented 4th?

The Structural And Functional Differences Between The Augmented Fourth And Diminished Fifth Intervals. The augmented fourth interval is called the tritone, while the diminished fifth interval is called the inverted tritone.

What is a simple interval?

In music, an interval is the distance between two notes. An interval of an octave or less is known as a simple interval, while any interval of more than one octave is a compound interval.

What can you play over tritone substitution?

The scale of choice to solo over tritone substitutions is the Lydian dominant scale. The Lydian dominant scale is a mode of the melodic minor scale. The altered scale is also a mode of the melodic minor scale. These 3 scales are related and contain the same notes, but start on a different root.

What is the tritone of C?

For instance, in the C major diatonic scale (C–D–E–F–G–A–B–…), the only tritone is from F to B. It is a tritone because F–G, G–A, and A–B are three adjacent whole tones. It is a fourth because the notes from F to B are four (F, G, A, B).

What is the most dissonant interval?

The intervals that are considered to be dissonant are the minor second, the major second, the minor seventh, the major seventh, and particularly the tritone, which is the interval in between the perfect fourth and perfect fifth. Figure 2: Dissonant Intervals.

Why are Tritones evil?

As its Latin moniker suggests, it’s an evil sounding combination of notes that’s designed to create a chilling or foreboding atmosphere. The interval was given a sinister name since listeners originally found it unpleasant and surprising.

What precedes a Neapolitan chord?

What is a flatted fifth?

The lowering (by a half-step) of the fifth degree of a chord; a device especially associated with early bebop.

How does tritone substitution work?

A tritone substitution is the substitution of one dominant seventh chord (possibly altered or extended) with another that is three whole steps (a tritone) from the original chord. In other words, tritone substitution involves replacing V7 with ♭II7 (which could also be called ♭V7/V, subV7, or V7/♭V).

How do you use tritone?

A tritone substitution usually takes the place of a dominant (V7) chord. So it turns this: C Dm7 G7 C into this: C Dm7 Db7 C. The easy explanation for why Db7 (the flat-II) serves as such a good substitute for G7 is that the chords share two notes: F and B.
