Tonality - Aural

• Is the music tonal or atonal ?
• If the music is tonal, is it functional (do cadences define the key?)
• Is it non-functional? Perhaps it still has a key signature, but it is best regarded as being 'on' rather than 'in' the key 
• Modal - in which case, name the key and mode it is based on. (Be careful, the music may not be modal throughout, or else may change modes as it goes on!)
• Pentatonic elements (In popular music - in these cases, name the key as well, for example, E pentatonic major
• Does the music modulate? (change key systematically), as in most classical works OR does it abruptly 'shift' from one tonal centre to another?
