CSO bassist Alexander Hanna, in solo light, finds singing voice in his grand instrument

Review: Often forgotten but integral, the double bass is the foundation of the orchestra. Without its supportive heft, the majestic edifice of the orchestra would crumble, and the driving harmonic motion it provides would be lost. So it was satisfying and just to see this taken-for-granted but vital instrument move to the front of Orchestra Hall’s stage on Dec. 19 in the hands of Alexander Hanna, the Chicago Symphony Orchestra’s principal bass.
