FANDANGO: For dance it is always fandango de huelva. There are two main types of melodies used for dance, with a final remate they call “por bulerias” but it never felt like buleria to me.

After you figure out how you will structure any falseta or estribillo (chorus that might repeat or go between coplas) and number of basic compases (4 measures usually is one compas) then you have these types of coplas (using the basic compasing for chord you say you know well already)

G7-C (depending on the melody, the C chord change comes right on the 3rd beat of the first measure, or on the 3rd beat of the 3rd measure)
So either beats 1-6, or you have just G7 for beats 1-6, then G7-C for the next 7-12 beats.
The rest is always the same.
C-C (1-6) C7-F (7-12)
F-G7 (1-6) G7-C (7-12)
C-C, C(orD7 passing)-G7
G7-G7, G7-C
C7-F, F-E

So you see the copla is always 6 compases long (or 5 1/2 if you do that short version in the beginning…depends on the melody and it is obvious). If you opt to play copla type falseta (such as the ones PDL does in his guitar solos), be aware they often have an extra 2 compas tag to square things off, so you need to cut those so it is clear 6 compases. And only do the 1/2 compas thing if there is a singer.

The other type of melody is the exact same length, but you go to A major instead of C major:
E7-E7, E7-Amajor
Am (minor)-Am, Am-E7
E7-E7, E7-A (major)
Am-Am, Am-E7
E7-E7, E7-A
Am-F, F-E
