Barre Chords and Transistions

This is a 5.45 minute video response from Mark Lincoln on Aug 28th, 2009

Question:

"Mcs88keys asked "I know how to construct all of the barre chords and how to find them on the fretboard. But I need help with switching cleanly, especially from an open to a barre chord. (like D to Bm or E to C#m) I never feel secure when I have to play a barre chord. I'm always hoping I nail it instead of knowing I will. Do you have any tips on what to aim for or some way to practice more effectively? Any help would be much appreciated. Thanks, Michael.""
