The Model O grand piano is the largest of our Steinway baby
grands. They differ from the salon and concert grands only in
terms of their shorter body housing. This means it offers
uncompromising sound while guaranteeing the ultimate in quality
and craftsmanship, opening up a world of limitless musical
expression. Just like all Steinway instruments, the smaller M-170
and S-155 baby grands follow the company founder’s aim “to build
the best piano possible”
