How do you lower the notes on a copper pipe xylophone? Urgent!?

Answer:

Pay more on the principal and refinance the balance for a longer duration.

Make the pipes longer. Note should be proportional to length. Do the math.

Can you buy a new pipe for the lowest note and cut all of the remaining pipes shorter? Making the pipes thicker by electroplating might help.

Thanks for the information about RainX. I got my cars' oil change about a month ago. They check for everything, including windsheild wipers.My car is a 2009,and I have to check the wipers more often because the heat of the summer down where I live , makes the wiper blades break faster.

I havent heard of any lubricant,--they are a throw away item as the elements especialy the sun makes them hard and you just replace.
