Note Frequency Table For Guitar Players
Note Names, Frequency and MIDI Codes Relationship
When producing music, especially with digital instruments, knowing the relationships among MIDI, frequency and note names is crucial.
This knowledge allows for accurate translation of guitar music into digital formats and vice versa.
On this page, you'll find an interactive tool and a complete table that will help you understand how to express a note by frequency, and, conversely, the frequency of musical notes.
Interactive Fretboard To Show MIDI, Note Names and Frequency
This fretboard shows the musical notes, the MIDI codes and their pitch frequencies in Hertz (Hz).
Click on some frets and select "show MIDI", names or frequency.
What is MIDI
MIDI (Musical Instrument Digital Interface) is a technical standard that describes a protocol, digital interface, and connectors, allowing a wide variety of electronic musical instruments, computers, and other devices to connect and communicate with each other.
Notes On The Guitar
Each note on the guitar, like on any musical instrument, can be represented by a specific MIDI code.
This code is a numerical representation of a specific note and its octave.
Notes On The Guitar
Each note in music corresponds to a specific frequency.
Frequency is measured in Hertz (Hz) and represents the number of cycles per second of a sound wave.
For example, the A open string on a guitar (A2) typically vibrates at 110 Hz.

MIDI, Notes and Frequency Recap
To recap, the MIDI code is a digital representation of the note.
The note name and octave number give a musical representation that musicians use.
The frequency is the physical property of the sound wave produced when the note is played.
Each note on the guitar can be described in these three ways.
Moving up a fret on the guitar increases the pitch by a semitone.
This change can be observed in the MIDI code (increases by 1), the note name and octave (changes according to musical scales), and the frequency (which increases).

FAQ
As a guitarist, why is understanding MIDI, note names, and frequency important?
Understanding the relationship between MIDI codes, note names, and their corresponding frequencies is crucial for guitarists, especially when producing music digitally. This knowledge allows for accurate translation of your guitar playing into digital formats and helps you grasp the fundamental physical properties of the sounds you create.
What exactly is MIDI, and how does it relate to the notes I play on my guitar?
MIDI (Musical Instrument Digital Interface) is a technical standard that enables electronic musical instruments, like a guitar connected to a digital setup, to communicate. Each note played on your guitar can be represented by a specific MIDI code, which is a numerical value linked to that note and its octave. This numerical representation allows for digital recording, editing, and control of your guitar performance.
What does 'frequency' mean for a guitar note, and why is it measured in Hertz (Hz)?
The frequency of a guitar note refers to the rate at which its sound wave vibrates, and it's measured in Hertz (Hz). Each unique musical note corresponds to a specific frequency. For example, the open A string on a guitar (A2) typically vibrates at 110 Hz. Understanding frequency helps in knowing the exact pitch of a note and its scientific basis.
How does moving up the guitar fretboard affect a note's MIDI code and frequency?
Moving up one fret on the guitar increases the note's pitch by a semitone. Consequently, its MIDI code will increase by 1, the note name and octave will change according to musical scales, and its frequency (in Hertz) will also increase. This consistent relationship means every fret progression has a predictable impact on all three values.
Can two different note names have the same MIDI code and frequency?
Yes, they can. Enharmonic notes, which are different names for the same pitch (like C# and Db, or E# and F), will always share the exact same MIDI code and frequency. The provided chart clearly illustrates this, showing that C#0 and Db0, for instance, have identical MIDI codes (13) and frequencies (17.324 Hz) because they represent the same sonic event.
How can I practically use the interactive fretboard and frequency chart?
The interactive fretboard helps you visualize and understand the direct mapping between a physical fret, its musical note name, its digital MIDI code, and its specific frequency. The comprehensive chart serves as a quick reference, allowing you to look up any note and see its corresponding MIDI code and precise frequency. These tools are valuable for deepening your understanding of music theory and digital music production.
