Examples
Proto-Germanic developed a strong stress accent on the first syllable of the root (although remnants of the original free PIE accent are visible due to Verner's Law, which was sensitive to this accent).
Such minimal systems are sometimes called pitch accent since they are reminiscent of stress accent languages, which typically allow one principal stressed syllable per word.
