About 50 Million Year Trip (Downside Up)
50 Million Year Trip (Downside Up) is Brant Bjork's six-minute song from Blues for the Red Sun (1992), one of the album's longer tracks. Every tab has Homme's guitars in C Standard (C F B♭ E♭ G C) and Oliveri's bass in C too, but the guitar parts spend most of their time up the neck: in the Songsterr tab the open low string is never played, and the lowest notes are spread over E♭, F and C in the middle octave, with the bass mostly on F.
This is the one song on the album that TuneLit measured clearly apart from the rest. The album sits about 19 ¢ flat (A ≈ 435.2); 50 Million Year Trip reads about 7 ¢ sharp (A ≈ 441.8), 26 ¢ higher, and its Tune button sets C Standard +7 ¢. Twenty-six cents is a quarter of a semitone, easy to hear on long sustained notes, so retune between this song and Thong Song if you play the album in order.
The audio check cannot confirm the low string here, simply because the record has so few open low notes, but the tabs all agree on C Standard.
Tip: Tune with the song's own button (+7 ¢), not the album's: on this track the album setting is a quarter of a semitone flat.
Step by step
Tune your guitar like the record
- Tap Tune like this: the tuner switches to C Standard, every string +7 ¢, the notes 50 Million Year Trip (Downside Up) was recorded in.
- From E Standard: Every string down 4 half steps. No tuner that knows C Standard? Clamp a capo across fret 4, tune to E Standard as usual, then take it off: every string drops to C 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. 50 Million Year Trip (Downside Up) sits 7 cents sharp on the record: at A 440 your guitar would sound that much flat against it, which Tune already corrects.
- Then play 50 Million Year Trip (Downside Up) along with the record: its lowest open note and your String 6 should ring together without a wobble.
