Mosaic rosette intensive course: design your own rossette

Mosaic Rosettes are one very specialised element in the artisanal process of guitar making. They are also a signature component that identifies both the guitar and its maker. Because of the complexity they entail, too often their construction is avoided, taking to standardised commercial solutions instead of handcrafting an own. In this course, taught by Jose A. Lagunar, we will learn how to build mosaic rosettes from scratch, what to take into account when designing the mosaics, and tips and secrets to give the final touch to our guitars with a high end rosette.

When: May 20th and 21st, 2017. Scheudle: From 10:00 to 21:00 hours, with a lunch break. Where: At Glissando (calle Castillo 4, Madrid, Spain) Price: 340 €. included 21% VAT icluding all materials. Number of students: 10 Booking: Fill this form above

Course development and materials:

We will combine theoretical contents with practical work, so that each student may make their own rosette during the course hours. All materials will be supplied by Glissando, including the holder that the student will use to insert their own designed rosette. Both the holder and the material used in its making will come to belong to the student for their own use after the course. Course dossier available to download here.
