Watch the Gypsy Bossa online guitar lesson by Andreas Oberg from Gypsy Jazz Duets
Andreas discusses the use of scat-singing as a practice tool as well as a performance technique. To begin, keep melodies simple and strong, making sure to stay away from repeating familiar finger patterns. Go slowly and focus on singing melodies based on guide tones. Additionally, you can try singing melody lines over the chords to glean new ideas for improvisation.
