Presentation skills in JHB include an emphasis on suitable gestures. You should know where to go slow, where fast, where to raise your voice and where to whittle it down to a whisper. There must be sufficient variety and modulation in your voice and never hesitate to inject elements of drama as you speak, highlighting salient issues with suitable gestures and dramatic pauses. While on the subject of gestures, it must be mentioned your body is an important tool in how you communicate. A straight and erect stance with arms freely hanging from your sides convey an element of confidence that invariably rubs off on the audience and you can conveniently mould them in any way you want - one of the points during presentation skills in JHB. After all, the basic thing you are taught in widely advertised courses in public speaking skills is how to win over an audience to your point of view. And, while you talk, always keep gesturing with your hands and modify your tempo according to the demands of your presentation. Gesture enthusiastically when you want to close an issue with a killer blow and let your palms flip from one side to the other as you prepare your audience for arguments that are about to be thrown at them. At times it has been observed that the distance between the presenter and the audience is so huge that listeners never have a chance to really bond with the presenter - he or she remains a distant entity right through the presentation. This could kill even the most daftly prepared presentation. So, if it is possible, try to circulate among the audience. The audience will also feel more involved by this move and will actively participate in the whole process while you as a presenter will be lauded for your presentation skills in JHB.
