I just came across a melodic 8-note scale combination that seems to sound naturally consonant. I've been reading a lot of scale e-books from the best authors including Dave Celentano, Adam Kadmon, Al Politano, Howard Wallach, Rich Cochrane, J.P. Befumo, or articles from Wikipedia and the internet but this scale structure was never formally listed or given much attention as far as I know so I decided to share it here in UG.

The scale formula is 1-2-3-4-5-b6-b7-7.

With C as the root, the spelling would be C-D-E-F-G-Ab-Bb-B-C and the closest diatonic key signature - in terms of it's sound (not statistical comparison), would probably be C major.

Here's a list of the triads and sevenths that could be built from the scale notes:


Try blending the scale with the chords above to see what happens and decide which chords and notes to emphasize most. After an hour or so you could end up with a song entitled "Andalusian Sunset" if you hit the right notes.

Just for the record, the scale could be quickly analyzed as the 6th mode of an F Melodic minor scale with an additional flatted 5th (starting from F), or a C Indian Sarasangi scale with an added flatted 7th (starting from C). The added b7th note (Bb) gives it an extra quality.

I'd like to know your comments about the sound of the scale - whether it sounds good to you or not and whether I should improve what I've written and post it as an article.
