Besides handling corporate training, Raphael also teaches the fundamentals of various instruments to adult learners who have a desire, but not enough time to commit to learning their instrument. In his own words, “As long as you have a desire to play an instrument, I will guarantee you can play it within 45 minutes with me.”

With his fun, energetic and engaging personality, he personifies the term “Edu-tainment”, where education and entertainment come together.

The In-sync team bonding experience we had was amazing. They really successfully facilitated our team, with majority of us not having prior music training, to play in a band and sound good! It is definitely worth a shot for those who are looking to have their team bonding done in a pleasantly unique manner.

Reuben Seah, Partner, TAT AXA

Good stuff! Very nice and patient people. The songs were easy to learn, and since it was easy, it wasn’t stressful, therefore fun haha. Makes me want to play in a band 🙂

My family and I were looking for something different to do on the weekends. We found In-sync and decided to give it a try. It was an amazing experience learning how to play instruments and even playing together as a band. Would definitely recommend this activity to my family and friends!
