2-chord tunes are a wonderful resource for a creative approach to music teaching! A vast number of melodies can be harmonised with just chords I and V – folk tunes, of course, but also melodies by major composers. See the teacher notes for a classroom project based on “Carnival of Venice”, which can be downoaded from our Easy/Classroom Ensembles page. This uses classroom, or other available, instruments and body percussion. In my software package, GridPlay: Creative Explorations Level 2, though, one of the fifteen grids (mini-apps) is IVTUNES, in which I’ve designed a self-contained resource for exploring the subject. Teacher notes in the accompanying e-book make it even easier for a non-specialist teacher to introduce a project, with suggestions for using the computer as an integrated classroom resource.
A first step to improvising and composing 2-chord melodies is aural recognition of the chord changes. In IVTUNES, I have designed a grid with which pupils can practise this skill. Words, music and chord symbols for these tunes are included in the e-book. As each tune plays back, accompaniment patterns based on the the two chords can be triggered, allowing experimentation until pupils are confident that all sounds right. Beneath each chord’s accompaniments, cells contain individual notes of the chord, stacked vertically. Pupils can use these chord tones to accompany one of the melodies. Later they can record a 2-chord backing track over which to improvise their own melodies.
