Band creates the ‘most relaxing tune ever’

A British band has worked with sound therapists to create a tune described by scientists as the “most relaxing song ever”.

Carefully arranged harmonies, rhythms and bass lines help to slow the heart rate, reduce blood pressure and lower levels of the stress hormone cortisol.

Manchester trio Marconi Union worked with sound therapists to create the soothing tune, which also slows breathing and reduces brain activity.

Scientists played the song to 40 women and found it to be more effective at helping them relax than songs by Enya, Mozart and Coldplay.

The study – commissioned by bubble bath and shower gel firm Radox Spa – found the song was even more relaxing than a massage, walk or cup of tea.

The women were connected to sensors and given challenging puzzles to complete against the clock in order to induce a level of stress.

They were then played different songs as their heart rate, blood pressure, breathing and brain activity were recorded.

Studies found Weightless was 11 per cent more relaxing than any other song and even made many of the women “drowsy” in the lab.

It induced a 65 per cent reduction in overall anxiety and brought them to a level 35 per cent lower than their usual resting rates.

The song features guitar, piano and electronic samples of natural soundscapes.

It is pierced throughout by buddhist-like chants that induce a trance-like state.

Lyz Cooper, founder of the British Academy of Sound Therapy, said Marconi Union had used scientific theory to make the “perfect relaxing song”.

She said: “The song makes use of many musical principles that have been shown to individually have a calming effect.

“By combining these elements in the way Marconi Union have has created the perfect relaxing song.

“The study found this to be the world’s most relaxing song.

“It contains a sustaining rhythm that starts at 60 beats per minute and gradually slows to around 50.

“While listening, your heart rate gradually comes to match that beat.

“It is important that the song is eight minutes long because it takes about five minutes for this process, known as entrainment, to occur.

“The fall in heart rate also leads to a fall in blood pressure.

“The harmonic intervals – or gaps between notes – have been chosen to create a feeling of euphoria and comfort.

“And there is no repeating melody, which allows your brain to completely switch off because you are no longer trying to predict what is coming next.

“Instead, there are random chimes, which helps to induce a deeper sense of relaxation.
