Watch the Modal Study #2 online guitar lesson by Jon Finn from Modal Rock Soloing
Jon explains and improvises using the C Ionian scale. Keep in mind that Ionian is really just a major scale. It’s actually challenging to get the scale to sound cool and hip while avoiding the "Doe, a Deer a Female Deer" quality that is so prominent in the scale's character. Play with the sound of it. Of course, learn it all over the fretboard.
