About my Music

My Goal

My goal as a bassist and composer is to find where the essence of the music lies, no matter the complexity of it,  and bring it forward so its available to everyone. I truly believe that no art form should be isolated from the others. Music should relate to images, stories and emotions.

To become better with my instrument and broader in my musical knowledge, every day.

My Journey

I am a doublebassist cur­rently liv­ing in Lis­bon, try­ing to learn and play as much as I can. I’m teach­ing dou­ble­bass at the “Villas-Boas Jazz School” from the Hot Clube de Por­tu­gal and just released my second album as a leader called "Truth Has To Be Given In Riddles".

The first one is called "Whatever It Is You're seeking, Won't Come In The Form You're Expecting"

I studied doublebass at the Conservatory of Amsterdam and graduated in 2010. Had some great teachers there and had the opportunity to study privately with great musicians such as John Clayton, Reuben Rogers, Larry Grenadier, Clemens Van Der Feen and Alejandro Erlich-Oliva. I won a couple of prizes and had the oppor­tu­nity to play at some of the biggest venues and festivals around the world.

Joao Hasselberg was feeling annoyed — feeling annoyed.Jul 5, 2015 @ 6:41
Acabei de fazer check-in do meu contrabaixo de viagem no aeroporto de Lisboa.
O bilhete foi comprado a uma companhia grega, mas quando cheguei ao aeroporto percebi que era a TAP a tratar do voo.
A pessoa do balcão de check-in quando viu a flight case (que tem um tamanho de uma mala grande e pesa 22kg) perguntou o que era e eu respondi "contrabaixo".
A pessoa foi buscar uma tabela em que cobrava 50€ por cada instrumento musical até aos 22kg, 100€ ate aos 32kg, (e por aí fora) e eu perguntei se era para um seguro ou se era para eles se responsabilizavam caso acontecesse alguma coisa. A resposta foi "não nos responsabilizamos por nada, é só uma taxa". Se for material de desporto ou outra coisa qualquer não existe taxa.

A minha pergunta ao mundo:
"Então mas eu compro um bilhete numa companhia e aparece-me outra (que eu não escolhi e com regras com as quais não concordei) a cobrar taxas que não fazem sentido algum?!
Mas está tudo doido?!?!"
