Piano lessons, a staple of American extracurricular activities, may be another tradition that is dying in the age of soccer and social media.

“When Jim Foster opened his piano store 30 years ago, he had 10 competitors selling just pianos.

When he closed Foster Family Music in late December, not one was still selling pianos in the Quad-Cities area of Iowa and Illinois.

“We did try hard to find a buyer,” Foster said. There were no takers.

Stores dedicated to selling pianos like Foster’s are dwindling across the country as fewer people take up the instrument and those who do often opt for a less expensive electronic keyboard or a used piano. Some blame computers and others note the high cost of new pianos, but what’s clear is that a long-term decline in sales has accelerated.

The best year for new piano sales in the US was 1909, when more than 364,500 were sold. But after gently falling over the years, piano sales have plunged more recently to between 30,000 and 40,000 annually.

Larry Fine, a Boston-based piano technician, consultant and author, said it is an indication of a changing society.

“Computer technology has just changed everything about what kids are interested in,” said Fine, who also publishes a website offering consumer information on new and used pianos. “People are interested in things that don’t take much effort, so the idea of sitting and playing an hour a day to learn piano is not what kids want to do.”

Youth sports demands also compete with music studies.

“Children these days are being recruited for so many other activities, whether it’s soccer, gymnastics or swimming,” said Robin Walenta, CEO of West Music, a music retailer with a chain of stores in Iowa and Illinois.”
