Lucas Ruiz de Ribayaz was a Spanish Baroque composer, vihuelist, and writer on music. "Luz y Norte" is not specifically associated with him. However, his most notable work is "Luces y norte musical para cifra de vihuela," which translates to "Lights and Musical North for Vihuela Tablature." This work, published in 1677, is a significant contribution to the Baroque music literature for the vihuela, an instrument similar to the guitar.
In "Luces y Norte," Ribayaz provides valuable insights into the musical practices of the time, including detailed instructions on how to play the vihuela and explanations of various musical terms. The work also includes a collection of compositions, offering a glimpse into the rich musical landscape of the Baroque era in Spain.
