yeah dude you can't solo without playing single notes, the whole idea of soloing is to playing single notes that will match the chords, and if you want to write a good solo, you just need to work with the notes that your chords are built
from and to use matching scales over them... for example: you playing a progression that goes like that"

Em A13| Gm7 C7/9| Em7 A13| C7/9

so a good idea for a base for solo can be:
(im not tabbing it, just giving you the notes)
E F# F D
E F# D
as you can see i just took the highest notes of each chord and played with them
the scale you can use here is mainly Em and any variation of it because you can also see the phrygian mode hiding here somewhere and more thinks that im not sure about them
