Here is a scale practice using octaves first played as doubles and next as arpeggios. Note on the tab (showing arpeggio only) that the D note on the 2nd string 3rd fret is played using the little or 4th finger on the left hand. This is very important to keep proper hand position.

Here are 3 basic scales that are used in flamenco. I use these for warm up.

--2-0------------------------------1-0----------------------------1-0-----------------------------
-------3-2-0---------------------------3-1-0-2-1----------------------3-1------------------------
--------------2-1----------------------------------3-2-0---------------------3-2-0----------------
-------------------4-2-0---------------------------------3-2-0----------------------3-2-0---------
--------------------------4-2-0--------------------------------------------------------------3-1-0-
------------------------------------------------------------------------------------------------------

The 1st scale is useful with A and E7 chords and good for Alegrias.
The 2nd is great with Am and E7 chords and nice for Farruca.
The 3rd is nice with A and Bd and useful in Bulerias.

Hope someone finds these useful.

The first exercise is really good - makes you think as you play
