  • Diatonic melody or harmony built from the 7 tones of a major or minor scale. a diatonic scale encompasses patterns of 7 whole tone and semi-tones.
  • Chromatic melody or harmony built from many if not all 12 semi-tones of the octave. a chromatic scale consists of a ascending or decending sequence of semi-tones.
  • Consonance concordant or harmonious combination of tones that provieds a sense of relaxation and stability in music.
  • Dissonance combination of tones that sounds discordant and unstable, in need or resolution.
  • Musical Texture the interweaving of melodic and harmonic elements in the musical “fabric”
  • Monophonic Texture Single melodic line without accompaniment
  • Polyphonic Texture two or more simultaneously and equally important melodic lines
  • Homophonic Texture one main melody accompanied by voices or instruments
  • Counterpoint a musical form involving the simultaneous sound of two or more melodies
  • Canon type of polyphonic compostition in which one musical line strictly imitates another at a fixed distance throughout.
  • Inversion (counterpoint) a variation of a melody or part in which ll ascending intervals are replaced by descending intervals and vice versa
  • Retrograde going backward; becoming worse
  • Retrograde Inversion the application of both retrograde and melodic inversion to a motive
  • Augmentation the statement of a theme in notes of greater duration (usually twice the length of the original)
  • Diminution the statement of a theme in notes of lesser duration (usually half the length of the original)
  • Binary From Two part (AB) form. Statement (A), counterstatement (B).
  • Ternary Form Three-part (A-B-A) form based on a statement (A), contrast or departure (B), and repetition (A). Also three-part form.
  • Sonata Allegro Form The form most often used for the 1st mvt of large works like symphonies and concertos. It is a large 3-part form, usually with an introduction, exposition (A), development (B), and recapitulation (A), with a coda.
