All I could find for it on Wiki was the following:
The famous D♭ D♭ G♭ D♭ A♭ jingle, sonic logo, tag, audio mnemonic (MP3 file of sonic logo) was produced by Musikvergnuegen and written by Walter Werzowa from the Austrian 1980s sampling band Edelweiss.[49] The Sonic logo was changed during the introduction of the Core brand.
I would guess the operative word here is mnemonic, which kind of makes you think of… The Chimes
Again, from Wiki:
The famous three-note NBC chimes came about after several years of development. The three note sequence G-E-C were heard first over Atlanta’s WSB.[6] The chimes outline what is known to musicians as a second inversion C Major triad. Someone at NBC in New York heard the WSB version of the notes during the networked broadcast of a Georgia Tech football game and asked permission to use it on the national network. NBC started to use the three notes in 1931, and it was the first audio trademark to be accepted by the U.S. Patent and Trademark Office[citation needed]. A variant sequence was also used that went G-E-C-G, known as “the fourth chime” and used during wartime (especially in the wake of the attack on Pearl Harbor), on D-Day, and disasters. The NBC chimes were mechanized in 1932 by Richard H. Ranger of the Rangertone company; their purpose was to send a low level signal of constant amplitude that would be heard by the various switching stations manned by NBC and AT&T engineers, and thus used as a system cue for switching different stations between the Red and Blue network feeds. Contrary to popular legend, the three musical notes, G-E-C, did not originally stand for NBC’s current parent corporation, the General Electric Company; although GE’s radio station in Schenectady, New York, WGY, was an early NBC affiliate, and GE was an early shareholder in NBC’s founding parent RCA. General Electric did not own NBC outright until 1986. G-E-C is still used on NBC-TV. A variant with two preceding notes is used on the MSNBC cable television network. NBC’s radio branch no longer exists.
Has anyone ever detected any ‘sinister’ and/or subliminal message in Intel’s seemingly inocuous – yet, admittedly, fairly effective – five notes?
That Werzowa guy must be a millionnaire by now!
