An acoustic guitar is a stringed musical instrument that produces sound primarily through the vibration of its strings, amplified by a hollow wooden body and a soundboard.

Acoustic guitars come mainly in two families: steel-string and nylon-string (classical). Steel-string guitars use steel strings and a narrower neck; they tend to produce brighter volume and projection and are favored in folk, pop, blues, and country. Nylon-string classical guitars use nylon strings, a wider neck, and a softer, warmer tone suited to classical repertoire and flamenco. Both types have a hollow body with a top (soundboard), back, and sides, a neck, fretboard, bridge, and tuners. Body shapes vary, with common steel-string designs including dreadnought, concert, and auditorium, while classical guitars retain a broader, more traditional form.

Construction and materials: The top is usually spruce or cedar; back and sides may be rosewood, mahogany, or maple. Bracing beneath the top, such as X-bracing on most steel-strings, shapes tone and strength. The fretboard holds the frets, and the bridge anchors the strings to the body. Neck width, scale length, and bracing influence playability and sustain. Finishes and hardware may vary, but most acoustic guitars rely on an acoustically resonant body rather than external amplification.

History and development: The modern acoustic guitar evolved from earlier European lutes and guitars in the 15th–16th centuries. The classical guitar was refined in the 19th century by luthiers like Antonio de Torres Jurado. Steel-string guitars emerged in the same century with reinforced bracing and larger bodies, expanding volume and versatility.

Playing and uses: Players pluck or strum the strings with the right hand and fret notes with the left. Techniques vary by genre; classical players typically use fingers, while other styles may use a pick. Acoustic guitars are used across many genres and as practice instruments.

Care and maintenance: Humidity around 40–60 percent, regular cleaning, and periodic string changes help preserve tone and neck integrity. Store away from extreme temperatures and direct sunlight, ideally in a case or on a stand.
