Modal Triad The Modal_Triad object generates chords in root position or inversions. It takes traditional chord names, chord function numbers, Roman numerals, tonicizations, etc. It even takes altered chords like Ebdom7b9#11. created by V.J. Manzo The modal triad object allows a user to play tertian chords of any quality. It receives scale data from the modal_change object and, when a tonic and mode is selected, the object receives the numbers 1-8 in its leftmost inlet to output the notes of the chord function associated with that number. For example, in major keys, the numbers 1, 4 and 5 are always major chords, 2, 3, and 6 are minor, so, if C Major is selected, a 2 sent to the modal_triad object will yield the notes of a d minor chord. For each selected chord, the notes of that chord are sent to the object’s 7 outlets in the following order: root, third, fifth, seventh, ninth, eleventh, thirteenth. Alterations like flat ninth or sharp eleventh are inferred by the chord function as it relates to the selected tonic and mode. The second inlet of the object allows the chord tones, received as pitch classes, to be restricted to one octave. The object also takes Roman numeral functions to yield chords. The standard capital Roman numerals for major, lower case Roman numerals for minor are used. A lower case Roman numeral iv in the key of C Major will yield an F minor chord regardless of the fact that chord has non-diatonic chord tones in it, the Ab. A capital Roman numeral with a plus sign next to it will yield an augmented chord, and a lowercase Roman numeral with a zero next to it will yield a diminished chord. In the same manner, a user can use letter names to build chords. A capital C will yield a C Major chord while a lower case e will yield an e minor chord. A capital C plus will yield an augmented chord and a lower case d zero will yield a d diminished chord. (set to C Major) This object also receives messages for tonicizations. A user can send the message Roman numeral V/5, to yield the 5 of 5 (a D Major chord in the key of C Major). The V Chord Tonicizations produce a Dominant 7th chord for each scale degree in the selected mode. That is, the root, 3rd, 5th, and 7th will form a Dominant 7th Chord exactly one perfect 5th above a given scale degree. The 9th, 11th, and 13th pitches of the chord are inferred according to the selected mode and NOT the mode from which the tonicizing chord prevails. Similarly the object allows other types of tonicizations including leading tone tonications and minor four tonicizations. Augmented 6th chords and Neopolitan chords can also be implemented. It even takes altered chords like Ebdom7b9#11. created by V.J. Manzo www.vjmanzo.com | www.vincemanzo.com
