Analogue and digital make beautiful music in Frankfurt

These brand new Fender electric guitars made to look road-worn are symbolic of the trend to combine old and new. But the Frankfurt Music Fair is not only about trying to return to rock'n'roll roots. The vast music trade show is also showcasing the ways by which the latest digital technologies can open up new possibilities for analogue instruments.

Bösendorfer and Yamaha joined forces to create this new high definition self-playing grand piano. Players can sit at the piano and tinkle the ivories; or, using a tablet, instruct the instrument to independently perform a recorded piece. With this high-tech invention, favorite tunes are accurately and faithfully played to a private audience.

Looks can be deceiving. This small Yamaha TransAcoustic guitar may not look like much, but it's the first acoustic guitar that needs no amplification or special effects to recreate a rich sound only usually achieved in superior sounding rooms. It is perfect for beginners who want to wow their friends when sitting around the camp fire.

Custom drum maker John Good went all the way to Tasmania to select the wood for the above bass drum. Known as the "wood whisperer," Good travels the world for unique timbers — from Italian cottonwood to Australian evergreen sassafras. The Tasmanian wood has a special grain and a particularly warm sound. A set of Good's drums costs €10,000 ($12,360).

The above Yamaha electronic drum kit features 50 electronic cymbals and drums and promises endless percussive options. The pads are particularly noise-absorbing to allow drummers to practice at home. They're also rather rubbery, which makes the rebound more natural. It's almost like playing a traditional acoustic drum kit.

A world premiere: "Metal Drum Power" presented its first drum kit made completely of stainless steel forged in Frankfurt. The inventor, Martin Irut, runs a steel processing firm. The hobby drummer covered the steel with a ceramic shell normally used to seal machines, which makes for a uniquely tight sound. A set costs up to €15,000.
