      Adding triadic melody to ground bass

      Lesson details

      Learning outcome

      I can develop a melody line from triadic harmony using passing notes, and considering rhythmic, textural and structural elements.

      Key learning points

      1. Triadic harmony can be used to build a melody by using one or two of the triad notes and the other in the bass.
      2. Melodies are often higher in the scoring so we can play them up the octave.
      3. We can develop the structure of a piece by adding in and taking out parts.
      4. One way to do this is to start with a monophonic texture and build to a homophonic texture.
      5. Adding passing notes to a melody adds interest and creates a smooth melodic shape.

      Keywords

      • Harmony - the notes or chords that accompany the melody of a piece of music

      • Octave - an interval of eight notes, eg. C to the next C is an octave

      • Passing note - a melodic note not from the chord, linking two chord tones

      • Monophonic - a texture that consists of a single line of music

      • Homophonic - a texture that consists of two or more musical lines moving at the same time (with the same rhythm)

      Common misconception

      An interval of a 3rd is three tones higher or lower than the first note.

      In C major (where pupils are counting the white keys), they should count the starting note and final note, plus any in between. So an interval of a 3rd is actually two tones higher or lower than the first note. An octave would be seven notes higher.

      Teacher tip

      The final task lends itself to pupils going in their own direction with their composition. It could be extended to include arpeggio/Alberti bass patterns. Pupils could also focus on their melody line and not complete the final task.
