mr_so&so's Essential Music Theory for Harmonica Players.
Here is a link to just the harp tab for chromatic scales in 12 positions. You can pull out any scales you want from there.
I forgot to put a legend for the tab in the document. Each ' indicates half step bend; + means blow; ob is overblow; od is overdraw.
The Roman numerals in the column headings indicate notes that fall into the I, IV, and V chords and also the flat 7th of the extended dominant seventh chords: I7, IV7, and V7. I just show only those chords since they are of greatest interest to blues players. If you study up on your chord theory you can use the charts to work out the tones for any chords.
My GoTip page, if you want to send me a tip.
