Open F Tuning Guide: Easy Chords, Scales, and Tabs

Open F is one of the most beautiful, overlooked tunings on guitar. Strum the open strings and you get a deep, mellow F major chord that rings with warmth - and because the strings are tuned down, it is gentle on your guitar and easy on your hands. Many players can make gorgeous music in open F using just one or two fingers.

This guide covers everything: how to tune to open F, easy one- and two-finger chords, scales with plain tabs, and tips for a rich, resonant fingerstyle sound.

How to read the tabs: The six lines are your strings (top = thin high string, bottom = thick low string). A number is the fret to press; 0 is open. This guide uses the popular low open F tuning: C F C F A C, low to high.

What is open F tuning?

There are two common versions of open F. We use the warm, low one: C F C F A C (low to high). Those notes spell an F major chord (F, A, C), so strumming the open strings gives you a full, deep F major - no fretting needed.

Because every string is tuned the same as or lower than standard, open F has low string tension. That makes it easy on the guitar and gives it a soft, mellow, resonant character - a close cousin of open C, just centered on F. (You may also see a higher version, F A C F C F, but the low C-F-C-F-A-C tuning is the most rewarding for acoustic fingerstyle.)

How to tune to open F

From standard tuning (E A D G B E), you lower five strings. Tune slowly and check each string.

Setup tip: Because several strings drop a long way, normal strings can feel loose or buzzy in open F. For a tight, clear sound - especially on the low C and F strings - use a slightly heavier-gauge string set. A small setup tweak (a touch more neck relief or action) also helps the low notes ring cleanly. The upside: low tension means open F is very gentle on your guitar's neck and top.

When it is right, strumming all six open strings sounds like one deep, warm F major chord.

Easy one- and two-finger chords

The joy of open F is how little you have to fret. Lay one finger flat across all six strings at any fret for a major chord (the name is the note on the 5th string, F). And many lovely chords need just one or two fingers because the open strings do the work.

Make it minor: The open A string (2nd string) is the "major" note of the chord. Barre your chord but fret that A string one fret lower for a minor sound.
Two-finger magic: Hold the open tuning and add just one or two fretted notes on the inner strings - you will discover lush, ringing chords with almost no effort. This is what makes open F so loved.

Scales in open F (with tabs)

Most guides skip this, so here it is. Start on a single string. Since the open F string is F, the patterns are simple. Play these on any F string (string 5 or string 3):

F major scale (one string)

F|--0--2--4--5--7--9--11--12--|

   F  G  A  Bb C  D  E   F

F major pentatonic (one string)

F|--0--2--4--7--9--12--|

   F  G  A  C  D  F

F minor / blues pentatonic (one string)

F|--0--3--5--7--10--12--|

   F  Ab Bb C  Eb  F

Tip: Let a low C or F string drone while you play the scale up high. That deep ringing foundation under your melody is the signature open F sound.

Tips for playing in open F

  • Sort your strings first. A slightly heavier set keeps the deep low notes tight and clear instead of floppy.
  • Let it ring. Open F rewards sustain - allow open strings to drone for a warm, full sound.
  • Use one or two fingers. Explore simple shapes first; open F sounds rich with very little fretting.
  • Use a capo. A capo moves all your easy open F shapes to a brighter key while keeping the same fingerings.
