A system for determining a musical modulation from a source key to a target key, such that the source key and the target key are selected from a cycle of musical keys. The system includes a relational tool and a bridging tool. The relational tool is capable of determining a primary modulation reference correlated to the displacement between the source key and the target key. Th e bridging tool includes a selected set of at least one bridge. The selected s et is correlated to the primary modulation reference. The present invention also h as a method for determining a musical modulation from a source key to a target key, such that the source key and the target key are selected from a cycle o f musical keys. The method includes the steps of providing a plurality of bridges indicated in a generic notation, wherein each bridge is correlated to a modulation reference; selecting the source key and the target key; determining a primar y modulation reference correlated to the displacement between the source key a nd the target key; selecting a bridge correlated to the primary modulation reference; and translating the selected bridge from generic notation to a standard musical notation.
