Major scales for Ukulele, 2 octaves, all 12 keys.

All 12-keys. Obviously we can't run "doe-to-doe" over two octaves in every key, but these all cover the entire 2-octave compass of the neck. The arrows indicate ascending or descending through the scale. These all start from the lowest root and go to the highest possible note; then you want to descend to the lowest possible note, and then back up to end on the starting note.

After you have "played" the scales, then "play WITH" the scales!

3-octave scales for 6-string bass

I use a low C instead of B, so for the very few notes that occur on the 6th string, just add 1 to the fret number. Fingerings are above the TAB staff, and the brackets indicate notes within a position. Probably redundant, but for me it's a helpful visual aid.
