What advice would you give to break in a new instrument?

Answer: In the beginning, play the instrument for no more than 10-15 minutes at a time. Swab it, return it to its case and keep the lid closed. A few hours later or the next day, you may repeat this procedure. Each week you may add five or ten minutes playing time. After about three months, you should be able to play it as you wish.

How can I reduce the risk of cracking due to temperature variations?

Should I use oil for the wood?
