What is a CT diminished 7?
As its name suggests, the common-tone diminished seventh chord has a fully diminished quality and shares one note with the chord it prolongs. This common tone is the root of the prolonged chord.
What is common tone technique?
Typically, a common-tone modulation does not use a pivot chord. Its mechanism is — on the surface — very simple: the listener first hears a chord in an established key; then, one note of that chord is sustained (or simply repeated), while all the other notes in that chord change to a chord in another key.
What are common tones in music?
In music, a common tone is a pitch class that is a member of, or common to (shared by) two or more scales or sets.
What is common tone modulation?
Common-tone modulation uses a sustained or repeated pitch from the old key as a bridge between it and the new key (common tone). Usually, this pitch will be held alone before the music continues in the new key. For example, a held F from a section in B♭ major could be used to transition to F major.
What is voice leading in music?
The term “voice leading” refers to the way in which individual voices move from chord to chord. The best voice leading occurs when all individual voices move smoothly. You can achieve this by moving between chords using the same note or moving up or down by a step in the inner voices of the chord, whenever possible.
What are passing tones in music?
A passing tone is a melodic embellishment (typically a non-chord tone) that occurs between two stable tones (typically chord tones), creating stepwise motion.
What is a Tertian leap?
Tertian Leap (root movement 4th & 5th apart) best used when changing between closed and open chords. keep one common tone, voice that has the 3rd in the first chords becomes the 3rd in the second chord, other voice moves by step. ( Tonal Harmony, pg 84)
Can you modulate without a pivot chord?
Direct modulation (also known as phrase modulation) is a type of modulation where a composer decides to move suddenly to a new key without using pivot chords or preparing the new tonic with its dominant.
What are modulations in music?
modulation, in music, the change from one key to another; also, the process by which this change is brought about. Modulation is a fundamental resource for variety in tonal music, particularly in larger forms. A short piece such as a song, hymn, or dance may remain in a single key.
What are the rules of voice leading?
The principles of voice leading can be summarize as follows: Keep common tones, Move voices by step, if possible, If you can’t move by step, move by smallest possible interval, Use contrary motion, if possible.
What is an NCT in music?
A nonchord tone (NCT), nonharmonic tone, or embellishing tone is a note in a piece of music or song that is not part of the implied or expressed chord set out by the harmonic framework.
What is a Tertian triad?
A major third on top of a minor third produces a minor triad. Finally, a minor third stacked on a minor third constitutes a diminished triad. A musical scale may also be analysed as a succession of thirds. The meantone temperament, a system of tuning that emphasises pure thirds, may be called “tertian”.
How do you take Dim7?
In order to build any Dim7 chord, you start on the root note and then stack m3rd intervals on top of that root until you come to the next root note (four notes later). Diminished chords are symmetrical because they consist of only minor 3rd intervals.
