For these experiments he constructed a great range of electrical oscillators to produce high-frequency currents, and coils tuned to set frequencies or wavelengths in order to discover characteristics of each energy level and particular uses to which each could be applied. He found that interlocking harmonics were similar to musical scale {Like Pythagoras and his 'Singing of Spheres' which he credited to his study of Great Pyramid.} and that his coils responded not only to transmissions of original waveforms, but resonated at harmonic intervals above and below original frequency. He had discovered harmonic nature of matter.

He felt ready to take next step in practical application of his theoretical discoveries. During an interview in 1894 he said:

“You will think me a dreamer and very far gone if I should tell you what I really hope for. But I can tell you that I look forward with absolute confidence to sending messages through earth without any wires. I have also great hopes of transmitting electrical force in same way without waste. Concerning transmission of messages through earth I have no hesitation in predicting success: I must first ascertain exactly how many vibrations to second are caused by disturbing mass of electricity which earth contains. My machine for transmitting must vibrate as often to put itself in accord with electricity in earth.” (3)

Most people still think Marconi invented radio. Tesla was given due credit for this invention by U.S. Patent Office, 25 years after his death. Tesla worked on Philadelphia Experiment. There are two movies on subject that surprisingly has a National Historic Plaque to commemorate it. One of these movies is a subterfuge and other has only minor merit. You could say they fictionalize and ridicule reality of why Tesla quit project. He knew they were engaged in creating rifts through time! Who really runs things?

If your guitar has a tremolo bridge, always remember that each string that you tune will go down in pitch as you tune next string. One solution to this is to over tune strings. That is to say, you may need to tune your low E string to an F in order to have it be around an E note by time you finish tuning other strings. Over time you'll get a feel for how much you need to over tune each string and it will become second nature.

If you play in a band, it is a good idea to always tune to same pitch. Standard pitch is 440 but some bands like to tune down to 430 or even 420 for heavier sound or vocal reasons or both. My point is that if you're practicing at 430 then you have a gig and your band tunes to 440, everything will suddenly sound different, your singer might not be able hit all notes he or she did at practice, your solos might even sound wrong. This is because everything is now a half step higher in pitch. Make things easy on yourself, pick a pitch and stick with it, at practice and gigs.
