E il pianista dov'è? In un'epoca in cui grammofono ancora non si conosce, un'invenzione cambia la riproduzione della musica. Si tratta dell'autopiano, un pianoforte che, grazie ad un meccanismo innescato da un rullo di carta, rilascia dolci note senza l'ausilio umano. Cos'è e come funziona lo spiegano Eduardo Rescigni e il critico musicale Piero Rettalino. Da "Tema musicale - Autopiano, uso e costume", 15.03.1984. Realizzazione televisiva di Enrica Roffi.
