The Challenge
Recording classical guitar (nylon string) presents some unique challenges. As with all acoustic instruments each classical guitar has its own sonic signature. As I hear them, classical guitars fall into two basic sonic categories: Even Shape and Bell Shape. Even Shape guitars spread the high, middle and low frequencies evenly as the sound leaves the guitar. Bell Shape guitars, on the other hand, tend to emphasize the lower mid frequencies is a bell shaped curve. This emphasis gives the guitar more volume or loudness but makes it difficult to record because it gives the guitar a hollow, out-of-phase sound. Another issue is compared to an acoustic guitar (steel string) the classical guitar (nylon string) has less definition. It is up to the player to develop a playing technique that gives the guitar its definition. So it’s important to capture the detail of the player imparts while avoiding the bell shaped emphasis of some guitars. Also, it’s best not to overemphasize the high-end in an attempt to add definition. Capturing an accurate, well-balanced and detailed sound image of the guitar is the primary challenge for me.
