In this test the goal is to evaluate the perceptual similarity between a reference sound and orchestrations. The orchestrations are combinations of musical instrument sounds that aim to imitate the reference sound. Each time, you will be presented 1 reference sound and 10 orchestrations. For each orchestration you are asked to rate the overall perceptual similarity in relation to the reference sound using the following scale: Very Different; Different; Fairly Similar; Similar; Very Similar. The orchestrations are presented randomly and are not ordered by any similarity measure.

After rating the perceptual similarity in relation to the reference, you will be asked to evaluate the overall diversity of the orchestrations using the same scale as before. The overall diversity is your evaluation of how different the orchestrations are from one another.

The test shouldn't take more than 15 minutes. Please read carefully the following information, even though you are used to doing such tests!

Instructions:

• Each reference sound has 10 different orchestrations.
• Rate the perceptual similarity of the orchestrations only compared to the reference on top.
• Try to rate the overall perceptual similarity of an orchestration without focusing on specific perceptual features such as pitch or timbre.
• Rate the overall diversity of the 10 orchestrations with reference to one another.
• Please take the test in a quiet environment.
• We recommend the use of headphones.
