The article further explains why the instrument works, stating that it can play any chord whose notes are multiples of a single fundamental. It also discusses the exceptions to this rule. The author suggests that a custom-designed keyboard could overcome most of the instrument's disadvantages. The author concludes by stating that the instrument is suitable for jazz due to its ease of improvisation and improved accuracy for 7ths. The author also provides a link for those interested in trying to play existing songs on the instrument.
Key takeaways:
- The instrument described uses just intonation instead of 12 equal temperament, allowing for modulation without detuning any intervals.
- Green keys on the instrument play the pitch, while purple keys change the tonality. The instrument is designed to make tonal sounds easy to play, while non-tonal sounds are either impossible or require deliberate choice.
- Compared to a piano, the instrument has several advantages, including faster pitch leaps, easier chord playing, better sounding minor sevenths, and easier improvisation. However, it also has disadvantages, such as requiring synchronized hands for tonality changes and awkward fingering for more than 4 notes.
- The instrument is designed to play any chord whose notes are reasonable multiples of a single fundamental, with a few exceptions. A custom keyboard could potentially fix most of the instrument's disadvantages.
