About Harmonious Wail:

Americana infused Gypsy Jazz on full tilt!

With over 30 years of touring the world, Award-winning instrumentalists, composers and vocalists Harmonious Wail are incandescent both on stage and off. The “Wail” travel with acoustic Mandolin, Bass and collected percussion through the rich musical traditions of Gypsy Jazz, Americana, Blues, Eloquent Rock, and Latin Jazz.

Their performances emote wit and grace and conviction to English, French, Russian, and Portuguese

“In the gypsy jazz field, no one does it any better than the Madison, Wisconsin based group Harmonious Wail”

(Jazz Review)

“Intense playing & sense of purpose that never wavers… a mind-altering experience.”

(The Washington Examiner)

Programs Offered:

Workshops/Community Outreach available as an addition to any performance.

If you can speak, you can sing! Maggie’s Method for Vocal Ease helps you develop your most natural and powerful voice. “Beginning” students learn to think like a singer and integrate breath, muscle control, and lyric interpretation to get the best results possible. “Workshops” are geared toward fun, risk taking, and adventures in singing. All styles welcome.

And Sims’:

Jazz Mandolin workshops explore the Gypsy Jazz music of Django Reinhardt and / or American Jazz standard.   Students try their hand at techniques such as “le Pompe” rhythm and explore approaches to melody and improvisations.  Students discover essential chords and arpeggios and learn the characteristics of Jazz and Swing

Custom workshops can be customized or created based on the individual event needs.

Harmonious Wail provided five workshops for Fergus Falls High School and Secondary Band, Orchestra, ALC and Choir (3 different choirs) students prior to their concert at Fergus Falls A Center for the Arts . The of topics and demonstrations ranged from improve, composition, business, inspiration for songs, practice techniques, improvisation  and copyright laws. The students were receptive and fascinated. One teacher commented that in one hour the students learned more than an entire semester because of the way Harmonious Wail involved the students and talked with them. Sims, Maggie & Jeffo you changed lives that day!

More Press Quotes
You’ll be smiling from the moment this CD starts to play…It is strangely reminiscent of Frank Zappa’s celebrated and just-as-jazzy Mothers of Invention … As a matter of fact, if this CD doesn’t set your toe to tapping and a smile on your face, you should probably get medication.
