GRAND PIANO SIZE COMPARISON - 272, 212, 170cm Steingraeber Grand Pianos

Buy me a coffee! https://www.buymeacoffee.com/bubiq I spend a night at the best piano shop in the world! The shop is a part of Steingraeber & Söhne piano manufactory in Bayreuth. I am comparing the sound of 3 Steingraeber piano, mod. E272, mod. C212 and mod. A170. From the longest on they make to the shortest one.
