TuneMap – Guitar Tuning Notes & Frequency Chart
About TuneMap – Guitar Tuning Notes, Frequencies & Tunings
TuneMap is a free interactive guitar tuning chart that shows every string note and its exact frequency. It helps guitarists explore standard tuning, drop tuning, open tuning, and other alternative tunings for 6-, 7-, and 8-string guitars. Each tuning displays real note names, DoReMi notation, and accurate frequencies in Hertz (Hz), making it easy to understand how pitch relates to tuning. TuneMap is designed for guitar players, producers, and educators who want a clear visual reference for guitar tuning and note frequencies.
Features of the TuneMap Guitar Tuning Chart
Designed for 6-, 7- and 8-String Guitars
TuneMap supports every modern guitar setup — from standard 6-string instruments to extended-range 7- and 8-string guitars. Each configuration displays the correct note names, octave numbers, and accurate tuning frequencies in Hertz (Hz). This makes it easy for guitarists to compare different string tunings and instantly visualize pitch changes.
Multiple Guitar Tuning Modes
The app includes four main tuning types: Standard Tuning, Drop Tuning, Open Major Tuning, and Open Minor Tuning. Each mode shows the correct string notes and pitch differences, allowing players to explore alternative tunings used in rock, blues, metal, and acoustic styles. Switching between tunings helps guitarists better understand tone, chord voicings, and transposition.
Switch Between ABC and Do-Re-Mi Notation
TuneMap lets you choose between letter notation (A, B, C) and solfège (Do, Re, Mi). This feature supports both classical and modern training systems, making the app suitable for international users and music students who prefer the Do-Re-Mi scale. It’s a practical way to connect music theory to real guitar tunings.
Choose Between Flats and Sharps
Guitarists can easily switch between flat (b) and sharp (#) note names. This is particularly useful since many digital tuners and notation systems display pitches as sharps by default. TuneMap ensures you can view your preferred note format — ideal for both traditional and digital workflows.
Adjustable A4 Reference Frequency
At the bottom of the app, you can fine-tune the A4 reference pitch (default 440 Hz). Adjusting this lets you match alternate tuning standards such as 432 Hz or 442 Hz, often used in orchestral or vintage recordings. This makes TuneMap a flexible tool for any guitarist who wants precise control over pitch calibration.
Clear Visual Layout for Easy Guitar Tuning Reference
All features are displayed in a simple, responsive interface that adapts to any device. The visual tuning grid shows each string’s note, frequency, and tuning difference, giving an instant overview of your entire guitar setup. TuneMap is both a practical reference and an educational resource for learning guitar tuning theory.
Why Accurate Guitar Tuning Matters
A well-tuned guitar is the foundation of good musicianship. Proper guitar tuning ensures that every note and chord resonates clearly, keeping your sound balanced and in harmony with other instruments. When your guitar is tuned accurately, you not only improve your tone but also strengthen your ear training — your ability to recognize pitch, intervals, and harmonic relationships.
Consistent tuning develops musical precision and helps you internalize correct pitch memory, which is essential for advanced playing, recording, and live performance. Whether you play electric, acoustic, or extended-range guitars, stable tuning allows better intonation, cleaner chord transitions, and more expressive dynamics.
Accurate tuning is also crucial when rehearsing or performing with other musicians. If each instrument follows the same reference pitch (A4 = 440 Hz), the entire band or ensemble will sound tighter and more professional. For guitarists experimenting with drop tunings, open tunings, or alternate reference frequencies such as 432 Hz or 442 Hz, maintaining tuning stability helps avoid pitch drift and phase issues in studio recordings.
In short, precise guitar tuning improves performance, recording quality, and listening skills. It connects the technical side of music — frequency and pitch — with the creative side of tone and expression. TuneMap was built to make this process clear, accurate, and visually simple for every guitarist.
