Cough - Articulation Series

Though a cough and a throat pop (which is basically a stronger throat tremolo) are virtually the same, the cough is exclusively used for blow notes. A general rule of thumb is that the only articulation we use for blow notes in a post war Chicago blues style is a cough. TA's and KA's tend to sound a little bit too "mouthy." So, experiment with a string of blow notes in improvisation and use some coughs to make them pop out. A word of caution though, the audience can hear those coughs, so use them sparingly.
