I actually used to play that same X shape pattern on guitar except that with 6 strings I always skipped the A and B strings, otherwise it was identical.Great routine today... After playing over an album I sat down with 80 bpm metronome, went thru both the minor scales I know in every different way I could think of. Even spelling out the names of tones in modes while proceeding with only every second beat. Then I doubled speed in the 80 bpm going back and forth the fretboard in this X-motion, advancing one fret at a time (sweep picking), such as:
-1-------------4-2-------------5-3-------------6-----
---2---------3-----3---------4-----4---------5-------
-----3-----2---------4-----3---------5-----4---------
-------4-1-------------5-2-------------6-3-----------
Btw now I understand the reason why bass fretboard is easier to memorize than guitar is not just the fact it's got less strings, but because it's symmetrical, while the guitar has that one odd string due to the E-F / B-C rule which means one has to learn so frigging many shapes for the chords on guitar.
Yesterday I played over Behemoth - The Apostasy, couldn't tell much more than each song using one note more than others (is that what they call the key?)
Today played over Swallow the Sun - Emerald Forest and the Blackbird, obviously a dynamic and memorable album that covered the whole bass fretboard pretty much.
The root note is usually the most used note in a song so if there were say, more B notes than anything else, the song will most likely be in B something. Being Behemoth I'd imagine it would be B minor or perhaps some diminished scale.
B Diminished: B C# D E F G G# A#
As you can see the diminished scale have nothing in common with the normal major/minor scales. They are just alternating between fulltone, semitone, fulltone, semitone... They even have 8 notes per octave compared to the modal 7. A diminished scale mode exists where the thing starts with a semitone instead of a full tone so it would go B C D D# F F# G# A.
