Mandolin Lessons

Boulder's home for private mandolin lessons. 


Robby Loeb (Beginner to Intermediate)

I began teaching music in Boulder, Colorado in 2003. I enjoy teaching students traditional Bluegrass songs as well as helping students learn and develop their own style. My intent is to find out exactly what my students want to get out of playing the mandolin, and what their learning style is so that I can adapt to it.

 Whether your focus is learning every bluegrass tune under the sun, how to improvise a solo, or just being able to hold your own at a jam with the rest of them, I can help you with that. I believe that each student can successfully achieve the expression of musical artistry through efficient practice habits, and proper guidance. Once the technical elements of playing an instrument are achieved, the door is wide open to making music as a form of art.

I studied under bluegrass legend Alan Munde at South Plains College in Levelland, Texas, and many other teachers along the way. 

I have been the director of the bluegrass ensembles at Harmony since it's inception in 2009. I am also the owner of the studio. 


Willie Gammell - Beginner to Intermediate

Willie Gammell.jpg

Willie has played in nearly every kind of band you can think of, and in nearly every city in the US. Willie plays guitar, ukulele, bass, mandolin, and banjo.

He played guitar in rock bands in high school. He then attended Shenandoah University, studying Jazz and Classical guitar before he heard the call of the road and joined up with the Southern Funk Orchestra. Willie played society gigs around DC and as a hired gun for demos and out of town bands.

Willie helped form the Soulutions, a world music influenced reggae band. Soon Willie found himself in NYC, giving lessons to people of all ages where ever the Subway would go. Here he formed one half of the duo The Galt Line, and toured coast to coast.

Back in the DC area, Willie taught, recorded, and toured with the psychedelic metal band The Neighbors. Recently Willie has been living in Boulder and teaching all over the front range.

Willie will show you that anyone can play music. He'll bring his love of performing and broad knowledge to you in every lesson.


Chris Herbst - Beginner to Intermediate

Chris Herbst.jpg

Originally from Vancouver BC, Chris is a dual citizen, multi-instrumentalist with an affinity for early jazz, swing, blues, bluegrass, rock, funk, country and various world musics. He began playing the guitar at the age of twelve and soon formed a garage band that played together every day till the end of high school. Chris attended Vancouver Community College and earned a diploma in jazz guitar. After college he was performing in blues and funk bands when he stumbled across a bluegrass jam. The Bluegrass bug bit him and he has never quite recovered. He learned to play each of the bluegrass instruments but Dobro wound up being the vehicle that has had him touring across the USA, Canada and Europe with a wide variety of acts. An armchair musicologist Chris loves to travel and always makes an effort to connect with local musicians wherever he goes. He has also traveled specifically for study including trips to Nashville and Kolkata, India. In 2016 after a 6 month stint living in New Orleans Chris moved to the front range of Colorado to play Dobro with popular touring act Thunder and Rain. Recently Chris has decided to stop touring, settle down next to the mountains in Boulder, teach lessons and raise his growing family. Chris has 20 years of teaching experience doing private and group lessons at music stores, folk clubs, out of his house and at music camps. He believes strongly in helping students learn the musical styles/repertoire that interest them while at the same time teaching the fundamentals of music including theory, timing, ear training, scales, harmony, technique, rhythm etc...
