A benefit for Big Brothers Big Sisters of Southeast Michigan Ann Arbor’s Brain Plasticity Ukulele Collective is a proudly intergenerational group, sharing instruments, knowledge, kindness, and talent across eras. Instruments you might hear in the music of the collective include not only ukuleles but also guitar, flute, percussion, harmonica, accordion, mandolin, mandola, bass, piano, and melodica. The group is inspired by the idea that music cuts across diverse cognitive capabilities and resources, including numeracy, language, and space perception.
