<b>Exploring tonal space</b>
 
This article focuses on the steps required to apply the ''"Tonal Space"'' interval system to a novel musical keyboard instrument.
 
''Tonal Space'' is a concept of musical intonation control that incorporates all modes of the overtone scale while allowing free modulation through twelve chromatic keys. The four-part ''"[[Expanding tonal space|Expanding Tonal Space]]"'' series (Parts I through IV) explains the development of Tonal Space in detail.
