Sanders Piano Co. has announced plans to wind down its business in Honolulu after about 42 years.

The company said Tuesday it will close after liquidating inventory of about 100 pianos in its store at 1500 S. King St. at the intersection of Kaheka Street.

Company founder William Sanders said trends affecting the piano sales industry, including electronic keyboards and diminishing music education in schools, were factors in the decision to close. Sanders also recently turned 80.

“It’s probably time for me to do something different — you might call it retirement,” he said.

Sanders founded the company in 1972 after moving to Hawaii in 1959 and working for a piano store owned by his uncle, Ed Jeffrey. Sanders Piano at one time had three stores, with locations at Windward Mall and Pearl Highlands Center. The company has three employees.
