Hi All. Firstly, I know people will comment telling me I either need to learn more or let my ears do the work (in terms of my methodical approach) bit I just really want some help in terms of what to learn and how to play with my current scenario. I play in an instrumental post rock band (think somewhere between the heavy riffs of mogwai, the warm organic noise of Godspeed, droning strings of Stars of the Lid and the odd time signatures of Slint) and recently one of our guitar players left the band. The existing guitar playing is working in the following way Using a bass amp in addition to his guitar amp to fill things out Always plays a lot of the roots mimicking a bass line in his playing Is tuned to drop C# which means he's reverse constructing odd chords and voicing Because of he dramatic nature of the music quite often I would just play roots on big fits along with the drums. Doing this created impact (so there is a point other than being lazy) there has also been sections where I would not play at all. In some sections of droning noise and reverb I would sometimes okay melody lines that would usually be based around the scale of the chord being played (underneath near infinite reverb) The problems I'm having is Quite often the scales I'm trying to bass basslines on wouldn't sound right because of the chords or voicings How do I learn and study harmony and melody better so I have options other than simply root notes and my usage of basing melodies around the octave note and 5th of the original root There is also a distinct lack of rhythm in some of this as the drummer also plays keys Can anyone offer help in where to begin to make this work and what I can do better?
