Trombone parts are typically notated in bass clef, though sometimes also written in tenor clef or alto clef. The use of alto clef is usually confined to orchestral first trombone parts, with the second trombone part written in tenor clef and the third (bass) part in bass clef.

Thanks for using the Apple Support Communities. I see that you're getting burst photos when you don't expect to. Your iPhone will only take burst photos when you press and hold on the exposure button in the Camera app. If you want to take a single photo, just simply tap on the exposure button once. Take a photo. Choose Photo, then tap the Take Picture button or press either volume button.
