Construction and Validation of the Seattle Singing Accuracy Protocol (SSAP): An Automated Online Measure of Singing Accuracy

The Seattle Singing Accuracy Protocol (SSAP) is a set of standardized tasks designed to measure pitch accuracy in singing. All singing tests are calibrated to the participant’s comfortable range through an automated range-finding procedure. In addition, we measure pitch discrimination ability and collect information on each participant’s musical background and self-perceptions of musicality. In the first part of the chapter, we review the conceptual organization of the SSAP and then describe in detail how the protocol is implemented as an online assessment tool. In the second part of this chapter, we report tests of validity.
