If we dig a little deeper, now we see that we've still not used the F note on our chord. This will be a particularly strong note, as it's the root of the chord, and it's also outside of our pentatonic scale. Just like you did in the previous section, practice incorporating this note slowly into your playing. Remember, it doesn't have to be musical at first, just get that note into you're playing and under your fingers.
Now let's take it one more step and look at the C chord as a C7 chord. C7 is spelled C-E-G-Bb, so now we can think about adding in the Bb over the changes. If we were to take the notes of these two chords and lay them out alphabetically, we would get a C Mixolydian scale, C-D-E-F-G-A-Bb-C. That's a lot to think about and can often sound very "scaley" when soloing. This is a perfect time to think about chord tone soloing. Repeat this process through all the songs in this course.
