Being a musician first and a guitarist second is the answer to an inspired musical life. If you only focus on the guitar, its repertoire and technique, then your musical life is going to be limited, and if you limit yourself, then you can expect times of little or no inspiration. Those ‘dry times’ can be very discouraging. Opening up to diverse musical experiences increases the emotional and technical resources available to the guitarist; and the ‘passion’ one can encounter in these experiences can lead directly to a more inspired personal performance.
The Guitar is a wonderful instrument, but don’t deny yourself a new musical experience.
