Alfonso Marin began his musical studies in the “Conservatorio Superior de Tenerife” (Spain), and afterwards in the “Conservatorium van Amsterdam” were he continued his classical guitar and vihuela studies under Lex Eisenhardt. From 1998 he devoted himself entirely to the study of early plucked instruments as the lute, theorbo and vihuela, continuing his studies in the same conservatory for five more years with the lutenist Fred Jacobs.

After his graduation he carried on with an intense concert activity as a soloist, vocal and instrumental accompanist as well as basso-continuo theorbo and archlute player in many Dutch renaissance and baroque ensembles, orchestras and choirs like “Les Perruques de Amsterdam”, “Arion ensemble”, “The Royal wind consort”, “Nieuwe Opera Academie (DNOA), “Alkaan Emsemble”, “Musica del Seicento”, “Doetinchemse Bach Vereniging”, "Amsterdam Symphonic Orchestra", "Concerto d'Amsterdam", "Barokensemble De Swaen", "New caldara Ensemble Amsterdam", "Venice Baroque Orchestra" among others. With the Wolkenstein Ensemble he has performed medieval music in Holland and Germany.

His collaboration with the soprano Valeria Mignaco is one of his most rewarding and fruitful musical activities, having performed with her in numerous recitals and festivals in Holland, Germany, Ireland, England, Belgium and Spain.
