Hmm, that’s a very good question. The Greeks had an instrument which they called a Kithara. By far the most significant work he inspired was Benjamin Britten ’s Nocturnal, Op. If you search on google then these two men come, Adolph Rickenbacker and George Beauchamp But they invented electrified guitar. These six-string guitars were still smaller than the modern classical guitar. In many history books, even some that are highly rated, you will read that the guitar was invented by the classical-era Greeks. This is due to a simple mistake. From the mid-18th century through the early 19th century, the guitar evolved into a six-string instrument, phasing out courses by preference to single strings. Not only was Segovia the most famous classical guitarist of all time, but he also literally invented the genre. And, the real roots of the guitar have been lost to time. Before his arrival, the guitar was a lowly instrument of the peasant classes. Bream was key in modernising the instrument, and his love of more hard-edged composers sent the classical guitar into new and uncharted territory (Bream’s 20th Century Guitar album is a must-own). The Classical Guitar is an instrument (like many others) that has evolved and changed over the centuries. It has many similar cousins like the Lute and the Vilhuela. An ornate guitar made by a Joakim Thielke (1641–1719) of Germany was altered in this way and became a success.
