Origin and Evolution of the Guitar
📌 The guitar evolved from ancient stringed instruments like the lyre, possibly invented by the Hittites around 1500 BCE.
🎼 Similar instruments like the sitar were used in India, potentially dating back over 400 millennia, featuring a resonating box made from a dried gourd.
🐫 The Arabs introduced the fretboard (neck) and called their instrument the 'alud' (meaning wood), which Spaniards later adapted to 'laúd' (lute).

Historical Development and Key Changes
📜 In Spain, the lute's neck was straightened, leading to the vihuela, which preceded the modern guitar structure used in taverns and courts.
🗝️ A highly regarded theory credits an Arab from Baghdad named Ziryab with adding a fifth string to the Arabic lute in the 8th century upon arriving in Córdoba.
⭐ Alfonso X the Wise documented two types of guitars in the 13th century: the Moorish guitar and the Latin guitar, with the latter evolving into the modern guitar and the vihuela.
🎸 The fifth string was officially added to the Spanish guitar around the 16th century, an innovation often attributed to musician Vicente Espinel.

Modernization and Contemporary Status
🎼 During the 18th century, technical improvements, notably the addition of the sixth string, moved the instrument closer to its contemporary form.
🛠️ In 1850, the first official Spanish guitar was created by Antonio de Torres Jurado, whose design modified the mandolin and became the basis for the modern classical guitar.
⚡ The 20th century saw the guitar become globally significant, adapting to various musical settings and leading to the invention of the electric guitar by Leo Fender due to technological advances.
🌳 Contemporary guitars are crafted from various woods, including mahogany, Indian rosewood, spruce, Canadian cedar, cypress, ebony, and pine.
