[QUOTE="Mushroo,
It is important to realize that scales are patterns of sound, not shapes for wiggling your fingers on the fretboard.
I have a hard time remembering them![/QUOTE]
Not really, just practice them, sing the note name as you play them, understand the relationship of all the modes. Play a major scale, sing the scale as you play it...use solfege, or sing out the names of the notes as you play them.. doing octave adjustments when the scale is too high or too low for your voice range....have a clear understanding by going to the piano and playing C major, from C to C all white keys...then start on D and play all the white keys, and have a solid understanding that the D dorian is simply a C major scale starting on the 2nd degree... do the same on all the modes... then start on E and realize that E Phrygian is a C major scale starting on the 3rd degree... do that for all the scale degrees... Major, dorian, phrygian, lydian, mixo, natural minor, locrian... always be singing them as well...then after a while you can go to your bass and do the same thing, it will be obvious where to put your fingers to play all the modes...most scales can be started with two different fingerings... and some even more when you use different fingering like 3 notes per string... don't get hung up in the fingerings... get hung up in the sounds and and musical shapes all the different modes...also... relate each mode to either the Major on Natural Minor scale, for instance: Dorian is a minor scale with a natural 6, phrygian is a minor with a b2, lydian is a major with a #4, mixo is a major with a b7... not sure what to call locrian...hahahahaha, a minor with a b2 and a b5, or a phrygian with a b5.. hahaha??? Play them from all over your bass.... ascending, descending, 2 octaves 3 octaves (6string players)... play them starting on the B string, E string, etc... play them on only one string... play them on one string using one finger...just play them... singing them when you can... play different patterns... NOT FINGER PATTERNS!... musical shape patterns: broken thirds...sixths, fourths, etc... play them in groups of 2, 3, 4, 5, etc...still singing the note name as you play... take a diatonic tune like "There will never be another you", and play all the scales starting on the root up to the 7th, then descend them from the 7 to the 1 then play them from the 3 to the 9, ascending and descending... play them as eighth notes so the chord tones (1,3,5,7) land on the down beat and the tensions and avoid notes are on the upbeats... then you realize playing a scale is really playing a chord with it's extensions...thats why their called "chord scales" Take Lydian for example: if you arpeggiate an F maj chord in thirds, you have 1,3,5,7,9,#11, and 13 (F,A,C,E,G,B,D)... now play the lydian mode, and realize you're playing 1, 9, 3, #4, 5, 13, 7...you've just brought the tensions down an octave so they fit into one octave...you'll realize after you nail the Gregorian Modes it is much easier to learn all the modes off the Melodic minor(jazz minor), because most of them are one note different than one of the Gregorian modes... have an solid understanding that C jazz minor is a minor scale with a natural 6 and a natural 7... sing them while playing them, using solfege or just the name notes... then you can go on to the modes of the melodic minor... dorian b2, lydian #5, Lydian b7, mixo b13, locrian natural 9... im not sure what the alt' scale can be related to..hahahahahaha. root, b9, #9, 3, b5, b13, b7.... play them all over your instrument... still singing!... do the same with the pentatonics... understand the different shapes of those as well.. NOT FINGER SHAPES/patterns, but musical shapes... (it will be very obvious where to put your fingers to play these scales... you never have to do any weird shifting... most of the scales fit within 4 frets/4 fingers with a few easy shifts... of course there are alternatives to all this... keep singing them. And always try to play all your scales as musical as you can, don't get hung up in running these patterns up and down like some kind of gym routine... the scales are simply a way to build up your vocabulary... matter of fact the musical phrase comes first, ... the music comes first... the scales just give us something to relate it to.... ok that's probably more than enough.... but you got to practice them, hear them, sing them... play a melody like "Beautiful Love" , and relate all the melodic phrases to a scale or chord, .thats when you realize the scales are part of what makes up western music... but its the melodies/phrases/ root motion/ diatonic and non diatonic chord progressions, etc... that come first... good luck, however, IMO, there is no short cut to nailing all your scales and understanding and hearing their function in any piece of music... you do have to practice them... a lot.
