 The Baroque guitar replaced the Renaissance lute as the most common instrument found in the home.The earliest attestation of a five-stringed guitar comes from the mid-sixteenth-century Spanish book "Declaracion de Instrumentos Musicales" by Juan Bermudo, published in 1555.The first treatise published for the Baroque guitar was "Guitarra Española de cinco ordenes" (The Five-course Spanish Guitar), c. 1590, by Juan Carlos Amat.
