Greetings Tapspace.  I'm looking for some insight on the conga notation for the River by Seth Adams.  Mainly, what particular technique/sound is desired for the notes with only a staccato dot above them?  I'm pretty sure the tenuto notes are open, the staccato with rooftop are "slaps" (but if I'm wrong please correct), just not sure about the others mentioned above. 

Thanks in advance for the insight.
