Have spent the last year trying to get the fret board under my fingers using pentatonics, modes, and playing those along with backing tracks and simply chord progressions I've come up with that seem to make sense from what I've picked up from learning the pentatonic scales. Ex. A minor - I play with A, C, D, E, G chords while noodling on top. Would like to spend more time learning the actual progressions, their names and beginning adding focused chord progression (and rhythm) practice to what I'd doing with pentatonics/modes. The end goal is functional knowledge of these progressions so I can start writing. Preamble Over: I've done some internet searching and have a start, but was just wondering what resources some of you have come up with for this sort of focused practice - websites, progressions you like. Writing with seven string in mind, standard tuning - just trying to get the process going a bit more. Thanks in advance.
