Instrument Tuning Reference Guide

A tone generator is an invaluable tool for musicians seeking precise instrument tuning. This comprehensive guide provides the exact frequencies needed for tuning various instruments and explains how to use our tone generator for optimal results.

Why Use a Tone Generator for Tuning?

Using a tone generator for instrument tuning offers several advantages:

  • Precision: Digital tone generators produce frequencies with exceptional accuracy
  • Consistency: Always provides the same reference pitch, unlike physical tuning forks that can vary
  • Versatility: Can generate any frequency, not just standard A440
  • Ear Training: Helps develop your ability to recognize pitch accurately
  • Accessibility: Available anywhere you have a device with internet access

Understanding Musical Pitch

Before diving into specific tuning frequencies, it's helpful to understand some basic concepts:

Standard Pitch Reference: A440

The international standard pitch reference is A4 = 440 Hz (often called "concert pitch"). This means that the A above middle C vibrates at 440 cycles per second. All other notes are tuned relative to this reference pitch.

Equal Temperament

Modern Western music typically uses equal temperament tuning, where the octave is divided into 12 equal semitones. This allows music to be played in any key without retuning, though with slight compromises in the purity of some intervals.

Octaves and Frequency Relationships

Each octave represents a doubling of frequency. For example, if A4 = 440 Hz, then:

  • A5 = 880 Hz (one octave higher)
  • A3 = 220 Hz (one octave lower)
  • A2 = 110 Hz (two octaves lower)

How to Use Our Tone Generator for Tuning

Step-by-Step Tuning Process

  1. Generate the reference tone:

    Use our tone generator to create a pure sine wave at the frequency of the note you want to tune to. For most instruments, start with A4 (440 Hz).

  2. Adjust your instrument:

    Play the corresponding note on your instrument and adjust it until the pitch matches the reference tone. When the pitches match exactly, you'll notice:

    • Minimal or no "beating" (wavering sound when two similar frequencies are played together)
    • A smooth, consistent sound
    • Resonance between the instrument and the reference tone
  3. Tune remaining notes:

    For some instruments like guitar, you may only need to tune one string to the reference pitch, then tune the remaining strings relative to that one. For other instruments, you may want to use the tone generator for each note.

Common Instrument Tuning Frequencies

Guitar (Standard Tuning)

  • E2: 82.41 Hz
  • A2: 110.00 Hz
  • D3: 146.83 Hz
  • G3: 196.00 Hz
  • B3: 246.94 Hz
  • E4: 329.63 Hz

Bass Guitar (Standard Tuning)

  • E1: 41.20 Hz
  • A1: 55.00 Hz
  • D2: 73.42 Hz
  • G2: 98.00 Hz

Violin (Standard Tuning)

  • G3: 196.00 Hz
  • D4: 293.66 Hz
  • A4: 440.00 Hz
  • E5: 659.25 Hz

Piano

  • A0 (lowest A): 27.50 Hz
  • C4 (middle C): 261.63 Hz
  • A4 (reference A): 440.00 Hz
  • C8 (highest C): 4186.01 Hz

Alternative Tuning References

While A4 = 440 Hz is the modern standard, some musicians prefer alternative reference pitches:

  • Historical tuning: A4 = 415 Hz (Baroque period)
  • Orchestra tuning: A4 = 442-445 Hz (some European orchestras)
  • Verdi tuning: A4 = 432 Hz (claimed by some to be more "natural")

Our tone generator allows you to set any frequency with precision, making it suitable for all tuning standards.
