Yamaha corporation is a Japanese Conglomerate that was founded in October 1887.  The company manufactures motorcycles, musical instruments, and more.  The logo hasn't changed much since its creation in 1967 which helps with the recognition of the logo.  The symbol has three overlapping tuning forks which create the shape of a Y.  I like the way this logo was put together because the symbol and the font are about the same height and everything is very uniform.  I also like the simple san serif font that was used for the logo.
