Ok I'll explain the situation.
I have to play a guitar solo during one section of a song. The problem is that during that section the other guitar only plays the D5 chord in an irregular pattern with considerable time between strummings.
The song is in the F#m scale and I already had a solo where I played over that scale and I thought it was good, but after recording it I felt that it didn't sound quite right and decided to change it, but I don't know how to make something that sounds good.
There is a lot of tutorials about soloing over a chord progression, but I haven't found anything about soloing over just a chord repeating over and over.
I don't know if I should create a chord progression for that part of the song and play over that or play over D lydian or if the time between the strummings of the other guitar is messing me up.
So I ask you some advice on how to play a solo over the same chord over and over.
