I have a page with a (slowly) growing collection of odds and ends for download. You can visit this downloads page here. In addition to technique routines from various bass players and some transcriptions of pieces, here are currently scale fingerings that I created for all major and (natural, harmonic, and melodic) minor scales. I created them, uploaded them, and then promptly deleted them from my computer. A few days later, I realized that there were a bunch of misprints in these scales, making reediting the parts extremely difficult. Aargh!
Grant Park Symphony Orchestra and Northern Illinois University bass instructor John Floeter also sent me some fingering charts for the same selection of scales, and these can be downloaded from that same page. He also found some errors on his own fingering charts, so you may have to do a little minor editing on either of these sets of fingerings.
A colleague of mine asked recently if I could make a available the same set of slace sheets without any fingerings at all. After a session spent highlighting and deleting in Photoshop (that’s what you get for deleting the original files), I now have these available. You can either visit the downloads page or get them directly from the links below.
