After over 40 years of development as a musician, designer and scientist, a fundamentally distinct approach to music came into existence. The passion of TESAM is modern music with roots in folk and blues. It can be regarded as rock 'n' roll or rock music. Although most of the inspiration comes from American music, a solid postitioning in Europe and the Netherlands has proven to be necessary.

A good example of the difference between American and Dutch culture is that in English there are only musicians, but in the Netherlands there is a division between 'musici' and 'muzikanten'. In other Western cultures there is a similar cultural division, but without the seperation regarding the definition of the profession.

The founder of TESAM decided to stop using this division in 2018, because he didn't belong to one of them due to his affinity. He therefore defines himself as a designing musician in the Dutch language.
