I only saw three percurssives out of the eleven possible ones in the ExtIPA chart, so I did something about it. The places of articulation in order are bilabial, labiodental, labioalveolar, dentolabial, bidental, linguolabial, interdental, (lower) alveolar, retroflex, palatal and velar/velodorsal. Most symbols are a representation of what two parts you should strike against eachother to pronounce it; w: Upper/lower lip ̪ : Upper/lower teeth ̺ : Tip of tongue =: Alveolar ridge ̼ : Tongue ɣ: Velum
