Abstract
IN THIS STUDY, THE ROBUSTNESS OF AN ONLINE tool for objectively assessing singing ability was examined by: (1) determining the internal consistency and test-retest reliability of the tool; (2) comparing the task performance of web-based participants (n  285) with a group (n  52) completing the tool in a controlled laboratory setting, and then determining the convergent validity between settings, and (3) comparing participants' task performance with previous research using similar singing tasks and populations. Results indicated that the online singing tool exhibited high internal consistency (Cronbach's alpha  .92), and moderate-tohigh test-retest reliabilities (.65-.80) across an average..
