Swedish is a language with different pitches which decide how to stress a word, similar to but not exactly like Chinese. This is also the case for Norwegian.
The so called akut accent or accent I is the Swedish accent, where the tone goes up slightly on the syllable with the main stress. The rest of the syllables have a lower tone and a weaker stress.
The magical grav accent or accent II is the one that we at sayitinswedish.com usually refer to as the pitch accent or musical accent, because of its uniqueness. Words with this accent are stressed twice, the tone goes up and down at the first stress and then slightly up again on the second stress. All other syllables, if the words has more than two, are weaker. This is what makes it sounds like Swedes sing when they talk.
