How to transform a theme (scalar mapping demonstration)
A demonstration of how to transform a musical theme, using scalar mapping, along with reharmonization and orchestration. This is a trailer for two longer videos:
- How to transform a melody (scalar mapping from Debussy to John Powell) *not yet released*
- How to practice transforming themes, scalar mapping (available on Patreon )
The changing character of this theme has a lot to do with changes to orchestration and harmony in addition to the melodic transformation that takes place moving between scales. However, just playing all the examples on the same instrument isn’t nearly as much fun...
Amazing Grace uses the tune “New Britain.“ Because the melody only uses notes of a pentatonic scale, it could have been measured in terms of an underlying pentatonic scale. However, for this video, I will only be mapping it based on an underlying major scale.
I also put these exercises together into larger set of variations for solo organ. Sheet music is available by request to Patreon members:
Update: by request in the comments, the examples from this video are now available to stream individually through Soundcloud here:
