2.3. Active Engagement
- Twenty items;
- Active musical engagement behaviors (e.g., “I keep track of new music that I come across”, “I often read or search the internet for things related to music”);
- Deliberate allocation of time and money on musical activities (e.g., “I don’t spend much of my disposable income on music”, “I listen attentively to music for _ hours per day”).
2.4. Perceptual Abilities
- Fifteen items;
- Self-assessment of a cognitive musical ability, most of them related to musical listening skills;
- Music listening skills (e.g., “I can compare and discuss differences between two performances or versions of a musical piece”, “I can tell when people sing or play out of tune”).
2.5. Musical Training
- Eleven items;
- Extent of musical training and practice (e.g., “I engaged in regular daily practice of a musical instrument including voice for __ years”, “At the peak of my interest I practiced on my primary instrument including voice for __ hours per day”);
- Degree of self-assessed musicianship (“I would not consider myself a musician”, “I have never been complimented for my talents as a musical performer”).
2.6. Singing Abilities
- Seven items
- Skills and activities related to singing (e.g., “After hearing a new song two or three times I can usually sing it by myself”, “I am not able to sing in harmony when somebody is singing a familiar tune”).
2.7. Emotions
- Nine items;
- Mainly active behaviors related to emotional responses to music (e.g., “I am able to talk about the emotions that a piece of music evokes in me”, “I sometimes choose music that can trigger shivers down my spine”).
