THE SERIES SPYGLASS HILL
PEBBLE BEACH, CALIFORNIA · DEL MONTE FOREST · ROBERT TRENT JONES SR., 1966
Five holes run out through seaside dunes. Then the round turns inland and spends thirteen under the pines of the Del Monte Forest. It is two courses stapled together — and the seam between them is the whole test. The anthem’s job is to hold one tempo across both.
Sandy seaside ground with Pacific views. The par-3 5th, Bird Rock, is the last hole where the ocean is fully in play — a downhill shot almost always into a seaside breeze.
Narrow tree-lined corridors, doglegs, sloping fairways, ponds guarding greens and undulating putting surfaces. Thirteen holes of position golf under Del Monte pine.
COURSE ANTHEM
Every course in the 248 library gets a walk-up song engineered on the same 3:1 grid at 112 BPM. Spyglass Hill’s is live — two masters in the player below, with the full library behind them.

THE 24/8 TEMPO SYSTEM
ONE BEAT = 0.536 S · 1½ BEATS BACK · ½ BEAT DOWN
Frame-by-frame video of tour professionals shows elite swings share an elapsed-time signature: the backswing takes roughly three times as long as the downswing. Measured on 30fps video, one of the four canonical tour tempos is 24 frames back, 8 frames down.
John Novosel, Tour Tempo (Doubleday, 2004). A Yale physics study (Grober & Cholewicki, 2006 — an arXiv preprint, not peer-reviewed) measured ratios of roughly 2.5–3.5 with club sensors, averaging near 3:1.
In a randomised trial of 26 golfers, four weeks of synchronised metronome training improved shot accuracy and consistency relative to a group that only practised. Separately, decades of rhythmic-auditory-stimulation research show the motor system entrains to an external beat.

At 112 BPM, one beat lasts 0.536 seconds. A 24/8 swing sits on that grid almost exactly: 1½ beats back, ½ beat down. Spyglass Hill’s anthem is engineered so the pocket of the song is the pocket of the swing — in the dunes and in the trees.
That last part is arithmetic, not a lab result — 24 frames ÷ 30fps = 0.80 s ≈ 1½ beats at 112 BPM. 112 BPM is a design choice; it does sit inside the 85–120 BPM band where human tapping and tempo preference naturally cluster.
USE THIS ANTHEM FOR
The drive down 17-Mile is long enough for the whole track. Arrive already on the grid.
Ocean holes reward a swing that doesn’t speed up in wind. Same 1½ beats back, every time.
The 6th tee is a different golf course. Let the tempo be the thing that doesn’t change.
One chorus is enough to find 3:1 again after a loose swing in a tree corridor.
Range work at 112 BPM: 1½ beats back, ½ beat down, every ball, both wedges and driver.
Spyglass hands them out. The reset is a tempo, not a thought.
THE TURN
Eighteen holes in order, each drawn in the grammar of the world it belongs to — dune profile and ocean hairlines for the first five, pine corridors for the last thirteen. Column height is the hole’s tournament yardage. The two colours meet in exactly one place: the seam between the 5th and the 6th. Running across all of it at one unchanging height is the tempo line.
On the numbers. Published rating and slope figures vary by tee set and by the vintage of the rating: across sources the championship-tee numbers span a rating of 75.4–75.5 and a slope of 144–148. We cite 75.4 / 145 as the resort Blue-tee card figure rather than presenting any single slope as definitive. Individual hole yardages differ by a few yards between the tournament card and the resort card (the 1st is 595 or 597; the 15th 130 or 132) — the strip above uses the tournament card throughout, and its eighteen yardages sum exactly to the published 3,514 / 3,527 / 7,041.
The PGA Tour has consistently listed Spyglass Hill’s 6th, 8th and 16th among the toughest holes on Tour. The 399-yard par-4 8th, Signal Hill — a fairway that slopes the wrong way, into a steeply pitched elevated green — is cited as the hardest hole on the course.
Spyglass Hill is traditionally described as the hardest course in the Pro-Am rotation: reported comparisons put it around 1.42 strokes under par against Pebble Beach at about 2.18 under, and a 2022 figure of 72.179 against Pebble’s 70.756. It is not fixed year to year, though — in 2025 Pebble Beach played as the harder of the two, and Spyglass ranked roughly the 39th-hardest course on Tour that season.
Having surveyed the new course, Bing Crosby said he felt Spyglass was three or four strokes harder than Pebble Beach from the back tees. He then bet Jack Nicklaus that Nicklaus wouldn’t better par there. Nicklaus shot 70 and collected $5 — a framed, signed five-dollar bill from Crosby commemorates it. Accounts differ slightly on how the bet was worded.
Inland, water guards the greens at the par-3 12th (Skeleton Island), the par-5 14th (Long John Silver) and the par-3 15th (Jim Hawkins). The 16th, Black Dog, bends left to right — a drive can run through the fairway, while trees on the right punish the tee shot that leaks left and short.
COURSE MANAGEMENT
Most strategy pages tell you where to aim. This one connects the decision to the rhythm: 24 units of structure — read, number, club, picture, rehearse — and 8 units of conversion. Step in and go. Same 3:1 as the swing, running one level up.
