The subject of week’s Name that Tech Tune challenge is a classical guitar solo. The question: Which company’s iconic sound was inspired by this song?

If you’ve never played before, here’s how it works: Listen to the sound below, and if you know the answer, send it to contest@geekwire.com.

Here’s the direct link to the MP3 file.

Our guest on the GeekWire radio show and podcast this week was Jeopardy! legend Ken Jennings, and we attempted to stump him with this one during our Name that Tech Tune segment on the show. Listen below to hear how that turned out. (You can probably guess.)

Here’s the MP3 for the segment. Once again, if you know the name of the company, send it to contest@geekwire.com. From the pool of correct answers we’ll pick three people at random to win copies of Maphead, the new book from Ken Jennings, signed by the author himself.

By the way, the answer to last week’s Name that Tech Tune challenge was Inspector Gadget, as many of you knew. Congrats to Deb Morgan, our winner, chosen at random from the pool of correct answers to win Kinect Sports Season 2.

Update, 11/12: The answer was Nokia. You can hear the classic Nokia ringtone toward the end of the song, Gran Vals. More background on this Nokia history page. Congrats to our winners, Aaron Bird, Andrea Meldrum and David Carnahan, who will each be getting a copy of Maphead.
