舒茲終其一生都在使用胡塞爾的現象學概念進行他的社會理論思考，他從不曾否定胡塞爾的思想對於人文社會科學基礎方法論的貢獻。本文指出，胡塞爾所提出的「自然態度的構成現象學」或是「現象學心理學」將作為說明舒茲與胡塞爾內在關聯性的重要線索。本文一方面說明在胡塞爾思想脈絡中的現象學心理學，另一方面則說明舒茲所賦予該學問的特質，繼而藉由帶出「相互調音關係」此一概念以說明舒茲如何為其自身的現象學心理學，亦即「純粹互為主體性的心理學」作了最佳的闡釋。

From earlier writings through later manuscripts Schutz has frequently referred to phenomenological psychology that originates in Husserl. Schutz holds that through phenomenological psychology Husserl makes magnificent contributions to the foundation of social sciences. What does Schutz mean by that and why has he frequently referred to phenomenological psychology, which he renders as “pure intersubjective psychology”? In order to answer this question we need to know first
what a doctrine of phenomenological psychology in Husserl is and then how Schutz inherits this doctrine for his use. In relation to that we would like to consider the question as regards what the specific character of phenomenological psychology in Schutz is. I hold that the notion of mutual tuning-in relationship that Schutz reveals in the article “Making Music Together”(1951), in which Schutz works on the musical phenomenon and works out the precondition of all possible communications is mostly worthy of attention in connection to the question.
