American Mandolin & Guitar Summer School

Marilynn, Ralph, Catherine, & Charlie

invite you to

AMGuSS 2025!

Below: AMGuSS Class of 2023 with Guest Artists, Choro das 3.

AMGuSS (The American Mandolin & Guitar Summer School) was founded in 1986 to promote the art of ensemble playing for the guitar and mandolin family instruments. Each session combines classical study with a dollop of Brazilian Choro music and other styles, in workshops, small chamber ensembles and an all-school plucked-string orchestra. AMGuSS is dedicated to improving the musicianship and broadening the musical horizons of its students.

One of the first American summer schools for mandolin & guitar, AMGuSS has run nearly every summer since 1986. With small classes, accomplished faculty, and an emphasis on fun, AMGuSS continues on until 2026. So the upcoming session is our penultimate one!

Our Faculty for 2025 includes:

Marilynn Mair - AMGuSS Director, mandolin

Marilynn Mair has shown the world what the mandolin can achieve in the hands of a skillful artist. Internationally praised for her concerts and recordings, she has established classical mandolin in chamber music circles worldwide, earning the title, “First Lady of the Mandolin”. Marilynn has performed at prestigious venues such as Carnegie Hall, the White House, and Lincoln Center, and internationally in Europe, Japan, China, and Brazil. She has released over two dozen highly acclaimed solo and ensemble CDs, and appeared on numerous compilations. Marilynn published her 224-page method book, The Complete Mandolinist, in 2008, and her bilingual choro method book for bandolim, Brazilian Choro – A Method for Mandolin written with Rio-based bandolimist and professor Paulo Sá, in 2010. Her third book, The 100 – Techniques and Exercises for Mandolinists, published in 2017, chronicles Marilynn's journey on mandolin with a series of original exercises and ideas to improve practice technique and performance. Marilynn's 4th book, The Complete Mandolinist Volume 2, includes over 100 pieces of music, presented in their musical context from the Renaissance to the present day. Marilynn's latest book, The Complete Mandolinist Volume 3 includes over 60 of her compositions along with downloads of over an hour of her performances. She is at work on a new book scheduled for 2025. Marilynn is an Emeritus Professor of Music at Roger Williams University in Bristol, Rhode Island, where she taught courses in music and cultural history specializing in the Americas. She spends time each year in Rio de Janeiro, where she researches and performs Choro music in rodas throughout the city. As well as founding and directing AMGuSS, Marilynn also founded and directs Enigmatica-- a plucked-string chamber ensemble now in its 24th year.  

Catherine Hawkes - mandola, guitar, orchestra conductor, chamber music coaching

Catherine is an Emeritus Professor of Music at Roger Williams University, where she established and directed the Instrumental Ensemble. Her interest in Medieval music led her to Indiana University’s Early Music Institute, where she earned a Doctorate in Music, as well as pursuing studio work in fine arts textiles. She was a producer for IU’s Focus record label and wrote several seasons of the Public Radio program Harmonia. Catherine was a founder of the early music quartet Melusine and the Smiling Dog Band and has performed extensively in genres ranging from opera to circus to jam band. She and her compositions have appeared on numerous recordings, and she released a CD of her own compositions, Natural History, in 2022. Catherine plays mandola and recorder with Enigmatica.

Ralph Costanza - mandolin, guitar, chamber music coaching

Ralph has been part of the AMGuSS faculty nearly since it began. Originally attending as a student in year 2, his enthusiasm and instructional expertise-- honed from years of teaching public-school music-- along with his charismatic leadership in after-hour jam sessions quickly earned him a promotion to faculty in charge of beginners. Known for his ability to engage players in developing technique and musicianship skills, whether in the 2nd-mandolin section of the orchestra or in chamber music coaching sessions, Ralph takes beginners under his wing to ensure that they experience AMGuSS to the fullest. And he remains the heart and soul of the AMGuSS informal night-time jam sessions, where his broad musical knowledge has lead to many a memorable experience.

Charles Moser - mandolin, guitar, chamber music coaching

Charlie joined the AMGuSS faculty in 2018, transitioning from student-who-knew-too-much to faculty and coach, introducing early-morning "mandolin yoga" sessions for those wanting to add even more playing time to their day.  He performs with Enigmatica, and as a soloist and band member in a variety of ensembles. Charlie started playing the mandolin one particular day in 1975, and has rarely missed a day since. He is sometimes distracted by the classical guitar, the electric bass, or his Fender Telecaster, and occasionally by his career as Charles V. Moser, Musician-at-Law. (BA in Guitar from Keene State College, JD from UNH School of Law). He is veteran of many commercially unsuccessful but artistically outstanding musical groups, covering styles from classical to cowboy to rock ’n’ roll. Early influences include Beethoven, The Tijuana Brass, and the My Fair Lady soundtrack.

Enigmatica Ensemble-in-Residence

Enigmatica is a New England-based mandolin ensemble directed by Marilynn Mair. Part chamber orchestra and part plucked-string double-quartet, Enigmatica performs a variety of music: Baroque, Brazilian, eclectic contemporary, and Americana music written by group members and friends. The ensemble features instruments of the mandolin family — currently: mandolin, mandola, octave mandolin, and 6- and 7-string guitars. Ensemble members come from Massachusetts, Rhode Island, and New Hampshire.
