Her father, Leopold Mozart, was her teacher in music and the piano. Nannerl was a child prodigy, exactly like her younger brother Wolfgang, and she followed in his footsteps.
She was exceptionally good at both playing the keyboard and composing, and at the time when she and Wolfgang were children, they frequently played as a pair all across Europe.
Nannerl’s existence as a singer and composer was tragically constrained by the constraints of society at the time, despite the fact that she possessed amazing musical skills.
During the 18th century, women were discouraged from pursuing jobs in the music industry. After Nannerl reached maturity and was of marriageable age, she mostly abandoned her musical studies and focused instead on finding a husband.
Nannerl proceeded to wed and raise a family, and although he kept playing the piano for his personal entertainment and taught music throughout his life, her musical career was never able to achieve the same level of success as that of his younger brother. It is impossible for us to determine whether or not he possessed the same level of skill as his younger brother.
Maria Anna Mozart had a reputation for her playing ability and innovative compositions, but it is difficult to say whether she was “better” than her brother Wolfgang Amadeus Mozart because they came from different families and followed different career paths.
Despite this, it is difficult to say whether Maria Anna Mozart was “better.” Both of these siblings were very gifted musicians and composers, and they both produced important additions to the canon of classical music, which is why it is imperative that this fact receives widespread recognition.
