Flashing back via an informal narration by Mozart to his wife while on their way to the first performance of Don Giovanni, Downing touches on significant events throughout Mozart's life, concluding with the opera's warm reception. The level of information offered here is appropriate to the format; troubles as well as triumphs are included. Downing's well-researched, decorative watercolors give a good sense of the milieu and its ornate trappings. An interesting, lengthy note is appended. Attractive; useful. (Biography/Picture book. 5-8)
