Ascetic rigor? This doesn't mean something like 'renounce' or even a 'lack' of something. No, it means, in philosophical manner (and especially in the historic Greek sense of 'Askesis'), a special kind of internal yearning, a special power wherein, despite all depressions, defeats, and failures you develop a new power to 'keep' to something, to create something. It's something like an obsession. Bach, Mozart, Schubert, they all (and their oeuvre) are filled from this phenomenon, and it's this spirit which keeps this music so vivid and alive – and fashioned for all times and generations.
