Jackson & Bam Bam are not abandoning the half-air half-sound technique.

Idol group GOT7's Jackson was learning some trot techniques from fellow Thai member Bam Bam and he mentioned he cannot discard the half-air half-sound technique which aroused so much laughters in the set. 

On the 19th March on MBC's broadcast show 'My Tutor Band Friend 띠동갑내기 과외하기 (referred to as' extracurricular band) Jackson advised Bam Bam that they shouldn't abandon the half air, half-sound technique as it's in their contract.

The program caught the public's attention when Bam Bam was dancing trot music with other members in their hostels. Bam Bam spurted out that the female trot singer Hong Jin Young dumped the idea of singing with half-air and half sound. Immediately Jackson told him off that it's part of their contract they have signed and they cannot do that.
During their 7 years, they have got mix it around. LOL! 

In reality their CEO JYPark is famous for singing with half-air half-sound techniques and he usually picks artists who have a perfect combination of this talent. It's a technique where you sing and breathe at the same time. This is a musical term when it comes to vocal singing and lessons. 

Meanwhile, the tutor band program is broadcasted every Thursday at 23:15pm where it's a program of learning through chest breathing and learning from others.
