Have you ever wondered why it takes that technician so long to tune your piano? Well, it's because there are lots of pins to adjust. How many? Here's a six step method to find out without counting each pin. It'll take about five minutes for you to find out. 1st-count the number of single bass strings; write that number down. 2nd-count the total number of notes that have duos, or two strings. 3rd-multiply that number by two to arrive at the number of pins in the duo section. 4th-now add number of notes that have singles and duos together; subtract that number from 88 to arrive at the number of remaining notes that have trios. You can count them if you want but this method is faster: 5th-multiply that number by three. 6th-add the singles, duos and trios pin quantities together. What number did you get? Share your results. Also, what kind of piano do you have: spinet, console, studio, grand, etc. Have fun! Note: we're counting tuning pins, not strings. That's a whole 'nuther thang.
