How much did Clementi charge for piano lessons?
Clementi charged one guinea for one hour. When you try to answer the question, “How much was our current money worth in the year, say, 1800,” different specialists come up with different answers because of the different approaches that can be taken. According to some calculations, a guinea in 1800 is roughly equivalent to $100 (U. S.) in 2007. Thus, it’s probably not far wrong to think that Clementi charged about $100 per hour for his lessons, and he often taught for sixteen hours per day. If he taught five days per week for fifty weeks per year, his annual income would have been approximately $400,000.
