Mozart, aged 13, is a piano virtuoso. He has signed a four (4) year contract with Beethoven to learn specific piano techniques to improve his skills. The terms of the contract stated that: a. Beethoven would teach Mozart piano free of charge; b. During the four (4) year period, Mozart could not accept performance engagements for the piano other than those under Beethoven; and c. Beethoven would employ Mozart to perform on stage for at least two (2) paid performances per year. Mozart accepted a performance engagement from Johann, to highlight his skills on the violin, as his income from Beethovens employment was insufficient for his support. As a result, Beethoven now wishes to sue Mozart for breach of contract. Required: Advise Beethoven. Note: You must answer question using IRAC method and the principles of Australian contract law.
