Set 3G complements Set 1 and Set 2 with the chords D major and B minor. This covers all 6 chords of the G major scale. With all 4 sets, you can accompany and improvise in the keys of C, F, and G, as well as in the parallel minor keys, both in major and minor. They can be used while standing or during dance (closed base, insertable mallet). Set 3G completes the chord functions of the G major / E minor (natural) scales from Set 1 and Set 2: G, Am, Bm, C, D, Em. Many children's songs are notated with chord symbols. The keys are mostly limited to C, F, or G major with the corresponding chord functions. With the chord glockenspiels, simple songs with arpeggios can be accompanied in practice.
