Craig Sean Teets, director of choral activities at the Moffat County High School, clearly was the man in charge Monday afternoon.
He directed Craig Middle School and high school students as they entered and exited the stage.
He cued the lighting technicians as soloists and groups took their places to perform.
His purpose: To prepare choirs from seventh-, eighth-, and high school levels for their last concert of the school year.
The concert, which is free of charge, takes place at 7 p.m. today at the Moffat County High School auditorium, 900 Finley Lane.
The performance has special significance for Teets.
"It's kind of the fulfillment of the year," he said. "We bring everyone together for the final concert."
About 100 students from the middle school and high school will perform selections from various musicals, including "Camelot" and "Les Miserables," accompanist Julia Foster said.
The students have been practicing for the event "off and on" since the year's beginning, she said.
And, in her view, they've made progress.
The choirs have "improved working together as a group," she said, adding that they also have bettered their pitch and tone since the school year's beginning.
"Certainly, they've improved on their tone quality," he said, adding that the choirs' dedication also made an impression.
The high school choirs will end their year with high scores from recent competitions.
At the Large Group Music Festival on April 17, the high school chamber and concert choirs earned excellent ratings.
The high school jazz choir earned superior ratings at both the Music Festival, hosted at the high school, and at the Greeley Jazz Festival on April 24 through 26 at the University of Northern Colorado.
"In retrospect, I don't think that there's anything else I could have asked of them," Teets said. "They've really pushed the envelope and excelled in everything they've done."
