About Mary Had a Little Lamb
Vaughan's short, punchy cover of a Buddy Guy song from Texas Flood. The riff is a single-note figure in E shapes that keeps landing on the open low string. On Vaughan's guitar, tuned a half step down, that string is E♭, and the whole song sounds in E♭.
TuneLit reads this track about 2 ¢ flat, right in line with the album, which sits at concert pitch, so the Tune button opens E♭ Standard at A 440. The low E♭ is one of the most frequent notes in the recording, and TuneLit's audio check hears it clearly as the lowest open string.
Because the riff keeps returning to the open low string, this song is an easy tuning test: if the guitar is still in E Standard, the very first lick clashes with the bass. The riff moves quickly around the lower strings, and with a light set tuned down those notes go sharp if you press too hard. Let the fretting hand relax and keep the attack in the picking hand, the way the record sounds.
Tip: Play the open low string with the record's first bass note: it should be a clean E♭, with no beating.
Step by step
Tune your guitar like the record
- Tap Tune like this: the tuner switches to E♭ Standard, the notes Mary Had a Little Lamb was recorded in.
- From E Standard: Every string down a half step. No tuner that knows E♭ Standard? Clamp a capo across fret 1, tune to E Standard as usual, then take it off: every string drops to E♭ Standard. Check each string again afterwards, since a capo pulls the strings a little sharp.
- Turn String 6 to String 1 until each shows ✓ in tune. Mary Had a Little Lamb sits at concert pitch on the record, so the tuner stays at A 440.
- Then play Mary Had a Little Lamb along with the record: its lowest open note and your String 6 should ring together without a wobble.
