Tuning a step and a half down
What C♯ standard is
C♯ standard keeps the intervals of standard tuning and lowers every string three semitones: C♯ F♯ B E G♯ C♯ from the 6th to the 1st. Chord shapes and scale patterns stay; the guitar sounds a minor third lower. It is a doom and heavy rock tuning: low enough to feel heavy, high enough to keep a normal guitar playable with a slightly heavier set.
Written in flats it would be D♭ standard, but with C♭ and F♭ in it nobody writes it that way: players say C♯ standard. Its drop version, with the 6th string a whole step lower again at B, is drop B.
How to tune to C♯ standard from standard
With the tuner above: tap Start, play each string the table changes and turn until the needle sits in the middle. By ear, without the tuner:
- Tune the 6th string to C♯2 first, from the tone of the string chip above (tap it with the tuner stopped) or a piano.
- 5th string: A2 to F♯2. The 6th string at its 5th fret (F♯2) should sound like this string open.
- 4th string: D3 to B2. The 5th string at its 5th fret (B2) should sound like this string open.
- 3rd string: G3 to E3. The 4th string at its 5th fret (E3) should sound like this string open.
- 2nd string: B3 to G♯3. The 3rd string at its 4th fret (G♯3) should sound like this string open.
- 1st string: E4 to C♯4. The 2nd string at its 5th fret (C♯4) should sound like this string open.
Then check the whole tuning once more with the tuner: retuning one string moves the neck, and the others drift a few cents.
On the same strings, tension follows the square of the pitch: every string keeps 71 % of its pull. Slacker strings buzz and read flat at the attack; for more than a whole step down, a heavier set (or at least a heavier low string) keeps the feel.
What one finger plays
Every chord shape you know keeps working; it sounds 3 semitones lower. A capo at the 3rd fret brings you back to standard pitch, which is how players in C♯ standard join a band that plays in standard.
Strings for C♯ standard
- Each string keeps 71 % of its pull on the same gauge: an 11 to 52 set brings back most of the feel of 10s in standard.
- The low C♯ at 69.3 Hz rings long; tune with the string fully sustained, not on the attack.
- A semitone higher: D standard; a semitone lower: C standard.
All six strings in standard and the other tunings: the guitar tuner. Any note at all: the chromatic tuner.
Then play something
The notes you tuned can go into Brumm as a short melody over a beat. Hum a line on top and it becomes an instrument.
