Rast: mode and dromos

Rast mode
The Rast mode has its theoretical basis and final on C, where the fundamental element 5x-rast is based. This mode has no fixed incipit, which may occur within the fundamental element (on C, E 1-comma flat, or G). The elemental structure is completed by a 4x-rast on G. The range can be extended by a 4x-rast on low G, establishing low B 1-comma flat as the mode’s sub-final.

The primary modal dominant is G, while E 1-comma flat serves as the secondary dominant. The following attractions may occur:
- D to D sharp, in ascending phrases and/or in phrases gravitating around the dominant E 1-comma flat;
- F to F sharp, in ascending phrases and/or in phrases gravitating around the dominant G;
- B 1-comma flat to B flat, nearly systematic in descending phrases.
