7.9 the Wood Determines the Sound?
7-102 7. Neck and body of the guitar 7.9 The Wood Determines the Sound? Mahogany! Maple! Rosewood! Men oft believe, if only they hear wordy pother, that there must surely be in it some thought or other [Goethe]. And the usual thinking is: “the electric guitar is a musical instrument made of wood. In all musical instruments made of wood, the wood determines the sound. The more noble the wood, the more noble the sound.” Goethe’s witch’s kitchen – a suitable location for deception and magic – holds more such articles of faith, but let us keep some distance from alchemy, and give physics the priority here: how does the body of the guitar vibrate, and in what way will the vibration of this body influence the sound? In the material-science course, every luthier learns about different tonewoods and their sound-determining material-parameters: “the denser the wood, the more brilliant, treble- rich the sound; the higher the stiffness, the longer the sustain (P. Day).” As if that were self- evident, this statement and similar ones are based on the assumption that the findings that are valid for violins and acoustic guitars apply to electric guitars, as well. If we now add that board of experts who listen to an electric guitar first of all without amplification, we quickly arrive at a conglomerate of teachings that, between them, could not be more contradictory. All the while two simple principles would really help us: 1) Compared to the acoustic guitar, the electric guitar functions very differently. Findings derived from the one type of guitar may not be sight-unseen applied to the other type.
