You may enjoy looking up micro-tones. Where western scales are made up of whole-tones and semi-tones, other cultures don't necessarily use the 12 semi-tone based scale system. Notably, Toxic by Britany Spears samples some Bollywood music, where the backing singing uses a bit of micro-tonality. You can often find different satisfying intervals, although they won't necessarily have the same cultural context/baggage associated with the sounds and therefore won't convey the same strong connotations that a diminished chord might.
