Dutch to English Marketing Marketing / Market Research Onomotopoeia

It looks like Finnish with all the umlauts missing, but I assure you it's Dutch.

This is a market research document in which a young woman is talking about herself and her family and hobbies. There's a picture of her playing the accordeon, and then she says:

"tataajapapaaa.. ik ben enorm gepassioneerd door muziek. ik zit in een folkgroepje. op straat proberen we mensen te amuseren. en ook op feestjes en recepties geven het beste van onszelf."

It's obviously onomatopoeia, but can anyone suggest an English version that doesn't look too weird? I thought of "dum-de-dum-de-dum," but it doesn't sound very accordeon-like.

I promise not to waste space by putting the answer in the glossary!
