Watch the Daylight online guitar lesson by Jeff McErlain from Essentials: Chord Tone Soloing
Yes, the video attached to this section is fairly self-explanatory, but let me take a minute to talk about what I call "The Three T's": Time, Tone, and Tuning.
Let's talk about time: First, it's extremely important to play in time, obviously, but it's often a major issue with players. Being able to start or end on a downbeat or an upbeat and locking with the time is essential. A great way to practice this is to play scales over the chord progression. In this case, run all the fingerings of your B major pentatonic scale using eighth notes, triplets, And 16th notes. Make sure they're nice and relaxed sounding, this is an excellent exercise to lock you into different rhythmic subdivisions over the song you're playing on.
Tone: While practicing the scales, make sure your notes sound nice and full. Try to make everything sound good and musical. You should always be thinking about music and sound - ask yourself as you're playing, "Does this sound good? Would I like to listen to someone else playing this?" Be very critical, but don't beat yourself up!
Tuning: Apart from your guitar being in tune, which I assume it will be, I'm referring to bends and vibrato being in tune. I would say this is the single most common problem I encounter with my students. There is a reason for it - it's difficult! So, when working on these two techniques, pay very close attention to your pitch. If you pay close attention to The Three T's and work on each one of them, I guarantee you'll see an improvement in your playing.
