Consonant intervals are usually described as pleasant and agreeable. Dissonant intervals are those that cause tension and desire to be resolved to consonant intervals These descriptions relate to harmonious intervals In music theory, consonances are traditionally divided into two groups: perfect and imperfect. Perfect intervals(1, 4, 5, 8)are perfect consonances, as seen in nic music of the Middle Ages. Imperfect consonances (3 and 6)are either major or minor Dissonances can be divided into sharp and soft dissonances. This division relates mainly to atonal music. Minor second and major seventh are sha dissonances In tonal music, non-diatonic intervals(diminished and augmented)are usually dissonances, but in jazz and other African-American music, the tritone is"neutral", in other words it does not require resolution to a consonance Table 5 Consonance and Dissonant Interval Perfect Consonances Imperfect Consonances Perfect Unison(1) Minor Third(3) Perfect Fifth(5) Major Third (3) Perfect Octave( 8) Minor Sixth(6) Major Sixth(6) Diatonic dissonances Chromatic dissonances (avoided entirely Perfect Fourth(4 Tritone (Diabolus in Music) Minor Second (2) Any Other Augmented or Diminished Interval Major Seventh(7) In C program, some restrictions are called to avoid chromatic dissonances and diatonic dissonances.

These descriptions relate to harmonious intervals. In music theory, consonances are traditionally divided into two groups: perfect and imperfect. Perfect intervals (1, 4, 5, 8) are perfect consonances, as seen in the polyphonic music of the Middle Ages. Imperfect consonances (3 and 6) are either major or minor. Dissonances can be divided into sharp and soft dissonances. This division relates mainly to atonal music. Minor second and major seventh are sharp dissonances. In tonal music, non-diatonic intervals (diminished and augmented) are usually dissonances, but in jazz and other African-American music, the tritone is "neutral", in other words it does not require resolution to a consonance.
