Re: Why are guitars with rosewood fretboards so prevalent?
Sorry to say this, but many you are making statements based on assumption... That´s good sometimes.... but, this isn´t one of those times, we´re talking about history here, and history is facts, not speculation
So: Why Rosewood (LOL, in 4000 characters or less, this should be interesting)
The forerunner of the guitar was the Lute....Lutes usually had one piece necks (commonly alder or oak) and were strung with pigs-gut or cat-gut, and VERY many lutes developed warping problems over the years. At some point in time it was discovered that making the fretboard from a separate slab added strength, and essentially solved this issue.
By the time the first spanish luthiers were making the first classical guitars, most european nations had become "seaworthy"..... On expeditions to south america, the Spaniards discovered ebony, rosewood, mahogany and other exotic woods, and of course brought them back to spain.
Luthiers started experimenting with these materials as soon as the supply bacame steady (until then the materials were for the royals only), and quickly fell in love with Ebony as a fretboard wood.. It´s fine, smoothe texture made playing near effortless on the then ultralow frets (frets were also made of gut wrapped around the neck for the first 200 years or so, btw...), and it´s tone was the perfect combination of snap, crackle, pop and grumble for the guitars.....Over in Mid-Europe (Mittenwald, Markneukirchen, both in Modern Germany...), these materials still weren´t known of, but it was discovered that Maple was also a wonderful wood for fretboards due to it´s rigidity, but it needed a finish....Ash was also very common, and Walnut wasn´t too rare, either....
Once the guitar had made its "final transformation" to what to this day is a standard classical guitar (Although every maker has their nuances and some have mildly differeing desings..but the general principle is the same) it also became more widespread as an instrument, and demand increased..... Ebony was expensive, rosewood much cheaper and looked similar enough, while having a similar stability, so rosewood boards were "invented".... Luthiers also noticed that rosewood was easier to work with than ebony, making it easier to get guitars built a bit faster (although then typical build times were 6 months and they cost you almost everything you had, not really an issue)
At some point in time the german and Spanish guitars got "cross-bred" and the Flamenco guitar with it´s bright, plucky tone and cutting voice was born.... but that´s kind of a side topic.....
At some point steel strings were discovered, and truss rods invented to counteract, the stabililty of the exotic woods was no longer enough....
Soooo, Why do we still use Rosewood today? There are other materialy which are stronger or sound better or , or or...
Because it´s become traditional over the last few hundred years, it sounds nice and round (in fact, the natural oils attenuating the highs make for a better beginner instrument IMO, because mistakes aren´t quite as instantly apparent.) Oh, and of all the dark woods, it´s the cheapest.... in today´s economy, very possibly the main reason (maple is even cheaper, but not dark)
