Boulder Timberliners Rehearsal Schedule Visitors are always welcome! Community UCC, 2650 Table Mesa Drive (Table Mesa Drive and Lehigh Avenue) in Boulder Tuesday evenings at 7:30 p.m. until about 10 p.m. Feel free to just drop in or call one of the numbers below. For more information, contact Don Reimer at 303-530-9008. Every rehearsal night is visitor night and you will always be welcome whether you just want to listen, sing along, or consider joining the chorus. You may visit as many times as you wish with no pressure to "sign up". No musical experience is necessary (although it doesn't hurt). The chorus has been singing in Boulder since 1949. Barbershop harmony is a style of unaccompanied singing in which three voices harmonize to a melody. The voice parts are called tenor, lead, baritone, and bass. The lead usually sings the melody. The tenor harmonizes above the melody. The bass sings the lowest harmonizing notes and the baritone provides in-between notes, either above or below the lead, completing the chords that give barbershop its distinctive four-part sound. The style is further identified by the use of chords that are harmonious (pleasing). Tuning is as nearly perfect as is vocally possible. The style is distinguished by uniformity of word sounds and a special emphasis on close harmony.
