Warren,

Depending on the frequency is how much tuning is involved, lower
frequencies are easier.  For a circuit to resonate it needs and input of
energy from somewhere whether it be a crystal set being strummed by the
airwaves or a Tesla coil being strummed by a spark gap.

If you have a frequency generator and scope use these to determine self
resonance of your coil with about a 100k resistor sitting between the
generator and coil and scope probe set to x10 and sitting right across
coil inside resistor.  Set generator to sine and look at some
frequencies on the scope tuning for the largest waveform.      Find a
small cap to put across the coil if you desire a parallel tank and use
an online LC calculator to determine the size of the cap for the
frequency you want.

Now how are you going to strum the device, I suggest to start at the
beginning with an Armstrong oscillator and build same with a single
transistor, you will learn a lot from this simple undertaking.  This is
the circuit most of the simple resonant devices like joule thief, solid
state Bedini etc are based on.  Could also go with a Colepitts
oscillator which also uses two coils but as a divider rather than linked
inductive/magnetic.

Without a capacitor it can be done but the Q will be low as one would be
reliant on inter winding capacitance. Could begin with a lecher line but
the Armstrong is more relevant.
