Netflix's ta-dum in Bangkok, Thailand: how Bow learns why a two-note sound logo sells a brand, and finds the finger number on the first note before her AI piano lessons

Bow is twelve and lives in Bangkok, Thailand, in an apartment where the television is almost always on in the evening. Her younger brother has a strange talent: from the next room he can tell which streaming service their mother has opened, just from the first sound. When he hears a deep, thudding ta-dum, he shouts that a Netflix show is starting.

That sound is a sonic logo, a tiny piece of audio linked to a brand. Netflix began using its ta-dum with the animated N logo in the mid-2010s, and it plays before the company's own series and films. It is only a couple of seconds long, yet millions of people around the world know it instantly.

In 2020 Netflix asked the film composer Hans Zimmer to create a longer version for cinemas, so that its movies on big screens would open with a richer, orchestral take on the same idea. The company also named its global fan event Tudum, borrowing the sound as a word. The two notes had become part of the brand's identity.

Bow found this fascinating and asked her uncle, who works in advertising, whether other companies did the same. He laughed and played her a list. The Intel bong, a five-note jingle created in the 1990s by composer Walter Werzowa, played at the end of countless computer adverts. McDonald's has used its whistled ba-da-ba-ba-ba melody since 2003.

The oldest famous example he showed her was the NBC chimes, a trio of tones, G, E and C, used by the American broadcaster since the days of radio. In 1950 they became one of the first sounds ever registered as a trademark in the United States. That meant other companies could not copy them, just as they could not copy a printed logo.

Why do companies bother? Her uncle explained that sound reaches people even when they are not looking at the screen, perhaps cooking or scrolling on a phone. A short, distinctive pattern repeated many times builds a memory. When the same notes appear on an advert, an app or a cinema screen, the brand gets credit without saying a word.

Good sonic logos follow a few rules. They are short, easy to recognise and simple enough to work on a tiny phone speaker or a huge cinema system. Many use only a handful of notes with a clear rhythm. Some brands also create a longer musical theme so the same idea can appear in adverts, games and events.

Bow wondered whether she could invent her own. That question pushed her to finally begin piano lessons, which she had postponed for years. Her mother picked TIGA ALPHA, an online piano learning app, which fit around her extra English classes and the long commute between home and school.

Practising with instant feedback

The AI piano teacher listens through the tablet and shows her immediately which note was off. It also suggests short drills when she repeats the same mistake. Bow likes that she can practise for twenty minutes in her room without anyone hovering, and that progress shows up as a simple chart each week.

For her project she learned to play piano versions of the NBC chimes, then the Intel notes, using lessons from the app's beginner piano course on intervals and simple melodies. Bow looks for the fingering digit printed under the first note of the jingle and curls the rest of her hand around that choice. With the right starting finger, the leaps feel natural instead of stretched.

Then she wrote one for her own family. It has four notes: a rising step, a little jump and a soft landing. She plays it whenever someone arrives home, and her brother now claims it is the official sound of their apartment. He also insists that he deserves a share of the royalties.

Her uncle pointed out that these little projects teach real marketing thinking. A brand has to decide what feeling it wants, calm, exciting or friendly, and then choose sounds that create it. Anyone who wants to learn piano and also loves design will find that sonic branding sits right where the two interests meet.

Bow shared her family jingle during music lessons at school, and the teacher turned it into a class exercise. Everyone composed a four-note logo for an imaginary company, from a noodle shop to a space agency. The class voted Bow's brother's suggestion, a sneeze followed by a chord, the funniest entry.

These days, when the ta-dum thumps out of the television, Bow listens differently. She hears the decisions behind it. Afterwards she opens her AI piano lessons, practises her scales and dreams up new four-note ideas, hoping one day to play music that a whole country recognises in two seconds.

Frequently asked questions

Q: What is a sonic logo? A: A sonic logo, sometimes called an audio logo or sound mark, is a very short piece of sound that a company plays with its name or picture logo, such as the Netflix ta-dum or the Intel bong, so audiences recognise the brand even without looking.

Q: Can a sound be registered as a trademark? A: Yes. In the United States the NBC chimes were among the first sounds registered as a trademark, in 1950, and many companies have since registered their sonic logos.

Many families now open an online piano lessons app between weekly classes. A good AI piano teaching app explains mistakes in plain words, which is what makes piano teaching with AI useful: the piano teaching app becomes a practice partner, and the online piano teaching application keeps a record of every session. Start with a piano learning course that matches your level, then let an AI online piano course support the days when you learn piano online on your own. Patient piano teaching, thoughtful music teaching, and a little daily effort are what help anyone learn music for life.
