What techniques, scales etc. would help me to create twinkly songs(ill list some below)? also, what should i do for bass? and what tone should i go for(for guitar and bass)?
thanks and ill post some songs below:
look at extended chords - particularly maj7s and add4s - and learn some songs by related bands. Look into fingerpicking and arpeggiating those sorts of chords played in predominantly major progressions, and make good use of fast slides in higher-register licks/riffs. Many of these bands use open tunings, too, so look into what common ones are used.

A good song to get a feel for it is Never Meant by AF.

tune to open c and feel it

your time will be better spent falling asleep with the mattress on top of you missing the blanket that was emma's love than learning dork guitar things
Start at the beginning.

Get familiar with a lot of alternate tunings and listen to a TON of first and second wave emo.

what open tunings are good? and what eq is good to get my tapping clear(ik doing them clean will help)?
