When it comes to teaching the arts through televison, all roads start with Leonard Bernstein.
His contributions to the great cultural show "Omnibus" in the 1950s and later his Young People's Concerts were brilliant. Without a whiff of condescension, he brought passion and intellect to decipher classical music for the general public as no one had done before or since. To many, his greatest role, above conductor and composer, was teacher.
If we lack a worthy musical successor to Bernstein, we have one in the visual arts. Bernstein's television progeny in this field is Simon Schama. His excellent eight-part series "Simon Schama's Power of Art " begins tonight on WGBH with looks at van Gogh and Picasso . There have been fine television hosts on art -- Kenneth Clark was wonderful in his dry way with "Civilisation" -- but there's no one like Schama to make it alive and immediate.
