Almost. We will put the signal of m into c. This is because m is
affecting (modulating) c. This modulation happens in a way set by the
.sync() function. So, the top two lines should be replaced by;

SinOsc m => SinOsc c => dac; //m affects what c plays. We listen to c.

All of the rest is right. If you set up m with something like;

110 => m.gain; //amplitude and thus modulation depth
3 => m.freq; //lfo frequency

Then it should work.

Once it works you can consider adding a envelope and maybe a loop that
plays a melody using your new sound.

No problem.

BTW; we do not need blackhole in this case because m is connected to c
and c is connected to the DAC. Anything that connects from the DAC
will be generating values because of that. We only need blackhole when
we want something to generate values (for example to use with .last())
but do not need to connected (indirectly) to the DAC. I think the
manual entry on blackhole should explain that. 

Hope that helps explain the underlying reasoning.
