walters Posted August 29, 2005 Posted August 29, 2005 The Diminished triad have a diminished 5th/augmented 4th which is a tritone What is a Tritone ? its only a diminished 5th or a augmented 4th intervals? The C Whole tone Scale has Three diminished 5ths or augmented 4ths or tritones Dominant 7th chords have a tritone The ii degree in harmonic minor is a Diminished triad and has a tritone What do these Tritones do ? are they pivot tones? are tritones just chromatic/altered tones? or are Tritones special and why?
Nightscape Posted August 29, 2005 Posted August 29, 2005 Tritones were once known as the Devil in music, and the church forbade use of them, possibly under the penalty of death. Fortunately, we live in a less suppressive society now... and are free to use tritones as we please. One interesting use of the tritone is a substitute note for scale degree V. For instance, a common chord progression in tonal music is I-V-I. In the key of C, if you were writing for full orchestra, the basses would probably be playing C - G - C as the bass notes of those chords. However, using this tritone replacement, you could have the basses play C - Gb (or F#) - C. This is a device common to early twentieth century composers like Stravinsky and Ravel. The progression I - bV - I can be found in pieces like Jeau d'eux by Ravel or also in Stravinksy's Petrouchka.
walters Posted August 29, 2005 Author Posted August 29, 2005 Thanks for the information So a tritone is a substitute note? Does every scale degree have a Tritone note? Whats the tritone of the first degree? whats the tritone of the 2nd degree? its a diminished 5th above the 2nd degree? whats the tritone of the 3rd degree? its a diminished 5th above the 3rd degree? whats the tritone of the 4th degree? its a diminished 5th above the 4th degree? When doing a Cmajor scale how do i add in Tritone notes to a c major scale?
walters Posted August 29, 2005 Author Posted August 29, 2005 what im trying to say is that in the key of C there is 7 tritones or more ? because each scale degree a diminished 5th up above the scale degree will produce a tritone so 7 degrees in a C major scale = 7 tritones in the scale?
walters Posted August 29, 2005 Author Posted August 29, 2005 C Ionian tritone is Gb flat D Dorian tritone is Ab flat E Phrygian tritone is Bb flat F lydian tritone is Cb flat G Mixolydian tritone is Db flat A Aeolian is tritone Eb flat B Locian is tritone is Fb flat These make a Diminished 5th interval above the scale degree so its a tritone in the C major scale having 7 new tritones?
walters Posted August 29, 2005 Author Posted August 29, 2005 But major keys have one tritone interval per major key A harmonic minor key has "4" tritone intervals per minor keys Why does harmonic minor have more tritones intervals than major keys?
