New Canaan Library starts the new year off on a high note with the return of the popular "Notes in Midwinter" concert series.

The series begins at 2 p.m. Sunday with a performance by Yale University's all-male a capella singing ensemble, the Duke's Men of Yale. Founded in 1952, the group has entertained audiences around the world with a repertoire that spans diverse genres and generations as well as music that members have written themselves.

Notes in Midwinter continues every Sunday afternoon until Feb. 8 with free concerts by musicians and ensembles performing music that ranges from chamber and classical to jazz and contemporary vocals. All performances are at 2 p.m. in the Adrian Lamb Room.

On Jan. 25, solo pianist Andrew Armstrong will perform works by Chopin, Brahms and more. On Feb. 1, flutist Lisa Arkis, harpist Wendy Kerner and guest cellist Katherine Cherbas will perform works by Bach, Chopin, Ibert, Vaughan Williams and others. And on Feb. 8, the Adrian Cunningham Jazz Quintet will perform music of jazz greats, including Louis Armstrong, Sidney Bechet and Fats Domino.

The concert series is curated by harpist Wendy Kerner.

All library programs are free and open to the public, but seating is limited and early arrival is recommended.
