What's the standard tuning for a 12-string guitar?
The standard tuning for a 12-string guitar is E3 E2, A3 A2, D4 D3, G4 G3, B3 B3, E4 E4. This mirrors the standard tuning of a 6-string guitar (E2 A2 D3 G3 B3 E4), but with each of those strings paired with another string, an octave higher, except for the B and high E strings which are tuned in unison.
Tuning a 12-string guitar can seem daunting at first, but understanding the string pairings is key. The lower E, A, D, and G strings each have an octave string paired with them. This means that when you pluck the E string, for example, you're actually playing two E notes: one in the lower register (E2) and one an octave higher (E3). This combination creates the rich, shimmering sound characteristic of 12-string guitars. The B string is paired with another B string, and the high E string is paired with another high E string, both tuned in unison. Because of the increased string tension, it's crucial to tune your 12-string guitar carefully and regularly. Over-tensioning the strings can damage the instrument's neck and bridge. Using an electronic tuner is highly recommended, especially for beginners, to ensure accurate tuning. There are also several helpful apps available for smartphones that can assist with tuning. Take your time, and double-check each string pairing as you go.How do I tune the octave pairs on a 12-string?
Tuning the octave pairs on a 12-string guitar involves tuning the lower four courses (E, A, D, G) to standard tuning and then tuning their octave counterparts an octave higher. The B and high E strings are tuned in unison.
When tuning the octave courses, it's essential to tune the standard string first. Then, tune the octave string to match. This is more easily accomplished using an electronic tuner, as the subtle pitch differences can be challenging to discern by ear. Ensure the tuner is set to chromatic mode, which allows it to detect all the notes rather than just standard guitar tuning. Pluck both strings of the course simultaneously and adjust the octave string until the tuner displays the correct note an octave higher than the standard string. For example, tune the low E string to E, then tune its octave counterpart to E, but an octave above the standard E. It is also important to be aware of intonation issues. A poorly intonated 12-string will sound noticeably out of tune, even after careful tuning. Check the intonation at the 12th fret of each string. If the fretted note is sharp compared to the harmonic, the saddle for that string needs to be moved back. If it is flat, the saddle needs to be moved forward. Intonation problems are more pronounced on 12-string guitars due to the increased string tension and the presence of octave strings. A properly set up 12-string will sound significantly better than one with poor intonation. Finally, consider using lighter gauge strings for a 12-string, especially if you are tuning to standard pitch. The increased tension of standard gauge strings can put excessive stress on the neck and bridge of the guitar. Lighter gauge strings will be easier to play and will reduce the risk of damage to your instrument.Should I use a specific type of tuner for a 12-string guitar?
No, you don't need a specific type of tuner designed *only* for a 12-string guitar. Any reliable chromatic tuner – whether it's a clip-on, pedal, or app – will work just fine for tuning a 12-string. The key is accuracy, not specific compatibility.
While a dedicated 12-string tuner isn't necessary, some tuners are *more* convenient for the task. Clip-on tuners are popular because they attach directly to the headstock and pick up vibrations, making them less susceptible to ambient noise. Pedal tuners are great for electric 12-strings and provide a clear visual display. Apps can be accurate, but rely on your device's microphone, which might be affected by background sound. Choose the tuner that best suits your playing environment and personal preference. The important factor is the tuner's ability to accurately detect and display the pitch of each string. Because a 12-string guitar has octave and unison pairings, precise tuning is crucial for avoiding a "warbly" or out-of-tune sound. Consider using a tuner with adjustable calibration (usually around 440Hz) to match other instruments you may be playing with. Also, make sure the tuner reacts quickly and clearly to small pitch changes to help you achieve the best intonation for each string pair.How often should I tune my 12-string guitar?
You should tune your 12-string guitar every time you play it, or at the very least, every day if you're playing it frequently. Due to the increased string tension and the doubled courses of strings, 12-strings are notoriously sensitive to going out of tune quickly.
The reason for this frequent tuning requirement stems from several factors unique to 12-string guitars. The sheer number of strings – twice as many as a standard guitar – dramatically increases the overall tension on the neck and bridge. This tension makes the guitar more susceptible to changes in tuning as the wood settles, reacts to temperature and humidity fluctuations, and even just from the force of playing. Furthermore, the close proximity of the paired strings means that even slight discrepancies in tension can lead to audible dissonance, highlighting any tuning imperfections. Beyond environmental factors, the age and quality of your strings also play a crucial role. New strings, in particular, tend to stretch significantly before settling into a stable tuning. Therefore, a new set of 12-string strings might require even more frequent adjustments during the initial break-in period. Over time, strings lose their elasticity and ability to hold a precise pitch, making older strings more prone to drifting out of tune. Regular tuning, coupled with replacing strings when they become dull or unresponsive, is essential for maintaining optimal sound and playability on your 12-string.What do I do if my 12-string won't stay in tune?
If your 12-string guitar won't stay in tune, the most common culprit is likely the strings themselves stretching, especially when new. However, other factors can contribute, including poor string installation, nut slot issues, bridge problems, or even environmental changes like temperature and humidity.
Start by thoroughly stretching your strings after installing them. Gently pull on each string individually, a few times, then retune. Repeat this process several times until the strings hold their pitch reasonably well. Also, ensure the strings are properly seated in the nut slots and on the bridge. The nut slots should be wide enough to accommodate both strings for each course (pair), without binding, as binding can cause strings to "catch" and then slip, leading to tuning instability. If the nut slots seem too tight, a qualified technician can widen them slightly. Similarly, check the bridge for any signs of wear or movement, which can also affect tuning.
Beyond string stretching and proper seating, consider the environment. Wood instruments are sensitive to changes in temperature and humidity. Drastic shifts can cause the wood to expand or contract, impacting tuning stability. Keep your guitar in a stable environment, ideally with a humidity level between 40-60%. Finally, if you've ruled out these common causes and your guitar still won't stay in tune, it might be time to consult a professional guitar technician. They can examine the instrument for any underlying structural issues or hardware problems that might be contributing to the problem.
Are there alternate tunings that work well on a 12-string?
Yes, while standard tuning is the most common, alternate tunings can unlock unique sonic possibilities on a 12-string guitar, offering different chord voicings, drone effects, and overall tonal textures. However, it's crucial to consider string tension when experimenting with alternate tunings to avoid damaging the instrument.
Alternate tunings on a 12-string often involve tuning down from standard (E3 E2 A3 A2 D4 D3 G3 G3 B3 B3 E4 E4), which reduces overall string tension and makes the instrument more playable. DADGAD, for example, is a popular choice, creating a rich, open sound perfect for Celtic and fingerstyle music. Other options include open tunings like Open D (D3 D2 A3 A2 D4 D3 F#3 F#3 A3 A3 D4 D4) or Open G (D3 D2 G3 G2 D4 D3 G3 G3 B3 B3 D4 D4), which make it easier to play slide guitar or achieve droning chord voicings. Experimentation is key to finding tunings that suit individual playing styles and musical preferences. It's important to remember that the octave strings on a 12-string can exacerbate tension issues when tuning up. Before attempting any alternate tuning, research the expected string tension and consider using lighter gauge strings if necessary. Online string tension calculators can be helpful tools for this purpose. Start with small adjustments and listen carefully to the instrument to ensure it is not under excessive stress. Always be mindful of the guitar's construction and limitations to prevent potential damage.Well, there you have it!
