Teodulo Mabellini was a pupil of the Istituto Reale Musicale in Florence.
When he was 19 years old, his opera, ‘Matilda di Toledo,’ was given at Florence (1836), with the result that the Grand Duke Leopold II. gave the composer funds to study under Mercadante at Novara.
His second opera, ‘Rolla,’ was given at Turin in 1840 with great success.
Mabellini settled in Florence in 1843, becoming conductor of the Societa Filarmonica, and eventually court maestro di cappella and conductor at the pergola (from 1848).
From 1859 to 1887 he was professor in his old school.
Some of his works include:
- Ginervra degli Almieri (Turin 1841)
- Il Conte di Savagna (Florence 1843)
- I Veneziani a Constantinopoli (Rome 1844)
- Maria di Francia (Florence 1846)
