Write a Song with Your Heartbeat

For the past 30 years, Taishin has made “earnestness” (認真) the core spirit of its brand, engaging deeply with consumers and helping Taiwanese people focus on what they truly think. Yet in today’s information-overloaded social media era, we found that when facing choices, people often care more about what others think than about what they feel inside.

When outside voices grow noisy, returning to that inward-focused earnestness matters even more, because it is the key to each person’s search for their true self.

A person’s heart speeds up in every “earnest moment,” and when we focus on ourselves, the thump-thump of our heartbeat becomes especially clear, like a moving piece of music. Taishin, which has always held earnestness as its spirit, hopes to support every earnestly beating heart through the melody and rhythm of the heartbeat.

Taishin launched the “Write a Song with Your Heartbeat” project. Using photoplethysmography (PPG), it turns a consumer’s phone camera into a heartbeat detector and, combined with AI, converts each person’s heartbeat BPM into musical BPM to create a song that follows the rhythm of their pulse.

The project lets consumers listen to a melody made from their own heartbeat, feel their inner rhythm as they focus on something, and rediscover their passion and sincerity for life. Whether in sports, studies, love, or work, Taishin accompanies every earnest Taiwanese person with a personal heartbeat single.

After the campaign went live, the interaction completion rate rose by 237%, and heartbeat songs were created more than 300,000 times. Thousands of comments on social media invited friends and family to join in, and professionals from many fields, including a karate gold-medal national athlete, a music therapist, and a pro basketball player, shared how it moved them. The campaign was also covered by multiple social and traditional media outlets.
