Exam ple 4 Diminished voicings
Here we see a similar principle but this time we’re looking at the Diminished
Σ 7th. There’s no real need for five forms here though, as the symmetrical nature of this chord means that each subsequent shape is identical, shifted
E up or down in m3rds, and equally that any note in each shape could be considered the root. Here we also see how a form can be repositioned to new string groups and finally we introduce the related voicing concept of ‘drop 3’, where R b3 b5 bb7 would become b3 R b5 bb7, spreading the voicing further while still representing each component note once only.
