Using the Library to Build Harmonic Protocols

To master the art of selecting tones that are specifically attuned to a client, feel free to consult the manual for the Library of Sounds or arrange a consultation with Dr. Calaba.

To proceed on your own, some basic choices and ideas are presented below.

  1. Choose a fundamental you would like to work with from the chart below entitled Fundamentals and their First Seven Overtones.  (For example, the note A.)  The fundamental and its first seven overtones are the notes you will be using in your exercise.  Tones are listed in the mathematical order in which they unfold.  The fundamental is usually sounded first.  It’s best to use to overtones in sequential order at first so that the brain learns the progression.  Then they can be used in any order.

Fundamentals and their First Seven Overtones

Fundamental 1st Overtone 2nd Overtone 3rd Overtone 4th Overtone 5th Overtone 6th Overtone 7th Overtone
A 110 Hz A 220 Hz E 329 Hz A 440 Hz C# 554 Hz E 659 Hz B 784 Hz A 889 Hz
A#/B♭ 116 Hz B♭ 233 Hz F 349 Hz B♭ 466 Hz D♭ 587 Hz F 698 Hz A♭ 830 Hz B♭ 932 Hz
B 123 Hz B 246 Hz F# 370 Hz B 493 Hz D# 622 Hz F# 740 Hz A 880 Hz B 987 Hz
C 65 Hz C 130 Hz G 196 Hz C 261 Hz E 329 Hz G 392 Hz B♭ 466 Hz C 523 Hz
C#/D♭ 69 Hz C# 138 Hz G# 207 Hz C# 277 Hz E#/F 349 Hz G# 415 Hz B 493 Hz C# 554 Hz
D 73 Hz D 146 Hz A 220 Hz D 293 Hz F# 370 Hz A 440 Hz C 523 Hz D 587 Hz
E 82 Hz E 164 Hz B 246 Hz E 329 Hz G# 415 Hz B 493 Hz D 587 Hz E 659 Hz
F 87 Hz F 174 Hz C 261 Hz F 349 Hz A 440 Hz C 523 Hz E♭622 Hz F 698 Hz
F#/G♭92 Hz F# 185 Hz C# 277 Hz F# F# 370 Hz A# 466 Hz C# 554 Hz E 659 Hz F# 740 Hz
G 98 Hz G 196 Hz D 293 Hz G 392 Hz B 493 Hz D 587 Hz F 698 Hz G 784 Hz
G#/A♭103 Hz G# 207 Hz D# 311 Hz G# 415 Hz B#/C 523 Hz D# 622 Hz F# 740 Hz G# 930 Hz
  1. Choose the octave range you would like to use. (Higher range usually is good for focus, lower range for relaxation.  Here are two charts to guide you—the first to help you choose an octave range and the second to help you hop around different octave ranges mathematically.

  1. Decide what kind of durations you need for the sounds in the protocol.  Short sounds are good for immediate acknowledgement that the goal has been achieved and long sounds are good for pauses between sets or consolidation periods. (Short and long sounds can be combined in the same protocol.)
  2. If you are uncertain what to choose, here is a basic example:

(Piano)  Fundamental of C:

  1. 261 Hz (short) immediate reinforcement tone
  2. 131 Hz (short) for use after a certain number of goals are achieved
  3. 66 Hz (long) during pause between exercises
  4. 131 Hz Overtone series (long) for closing eyes after exercise and consolidating


         131 Hz Cycle of 5ths (long) for closing eyes after exercise and consolidating
