Mozart was six.
Mozart died in his 30s in Vienna
Mozart mostly used the piano and the violin, as these were what he was principally tutored in.
Mozart was 4 years old when he started playing the clavichord. He was taught by his' father.
i think about around 5 or so because that's when he started playing the organ
probally when he was at primary school. Mozart was born into a musical family. He was exposed to classical music from birth and by the time he was age 4 or 5, he was able to read and write musical compositions.

started playing piano at age 4
I believe you are thinking of the harrkpsichord.....
During Wolfgang Mozart's childhood, Leopold (his father) 'cut down' his age as a publicity stunt to make him seem younger than he was so the exact age Mozart started playing is doubtful. Some claim he was three, others put it at six, either way it's way more impressive than what many people accomplish by the time they're sixty!
Mozart begin playing instruments at the tender age of 6 years old. He could play the violin, harpsichord, piano, and other keyed instruments of the time.
Mozart was performing regularly in public by age 5. His sister, Nannerl, started almost as early. It is sometimes written that he was four when he started, but that is because his entrepreneurial father shaved a year off his age when presenting him.
At the age of three, it was apparent that Mozart was a musical prodigy and he was taught to play the harpsichord, violin, and organ by his father. More about Mozart can be found at - http://en.wikipedia.org/wiki/Wolfgang_Amadeus_Mozart
