(scroll down to find the interval ear trainer)
because I want to improve my ability to trasfer melodies on to the fretboard and improvise, but I don't know how I should go about learning the scales.
What would be the best way to learn them that would provide the most flexibility? Should I learn the pattern of the scale from the first to the twelfth fret, or should I learn the positions of the scale, or learn all the notes by name on the fretboard and remember what notes each scale consists of (seems the hardest). Any disadvantages to any of these?
I know a guy who has never learnt any of this and just knows where to put his fingers instinctively. He says he developed it just by figuring songs out by ear. Would that be the way to go?
Any help is appreciated.
