Melody is very important in the music that I play. Many guitar players focus on harmony first, often at the expense of melody. I always try to make the guitar sing, perhaps this is because singing has also been an important part of my musical experience. I often use the voice as a vehicle for the melody or a different harmony, improvising the vocal "colors." Sometimes the humming will be replaced by real lyrics later on, even though many of the tunes I write are songs without words or voice parts.
