A Scroom’s frequency range is the Hz band shown on its Index card. During a catch, hold and move the tuning control until the waveform settles on the target frequency. Frequency tells you where to tune and whether your instrument can cover the band; it does not tell you how often that species spawns.
The official SCROOMS description confirms that tuning happens before the Scroom commits and says faster Tune Speed makes that stage quicker. Exact card ranges come from live-Index community readings. Use the numbers below as a dated field reference and replace them with the value shown in your current server if the card differs.
Songkeeper’s Grove frequency bands
18.7–31.2 Hz
Redcap (Common), Florabella (Wondrous)
22.5–37.5 Hz
Toastbud (Common)
26.2–43.7 Hz
Sunbrella (Uncommon), Funglebee (Wondrous)
30–50 Hz
Gloombell (Common), Mistdrop (Uncommon)
37.5–62.5 Hz
Acornub (Uncommon), Faebud (Wondrous)
41.2–68.7 Hz
Dewleaf (Rare)
45–75 Hz
Bluebell (Common)
48.7–81.2 Hz
Bloomcap (Uncommon)
52.5–87.5 Hz
Bramblepip (Rare)
71.2–118.7 Hz
Burlcap (Rare), Koroom (Fabled)
These overlapping bands show why a frequency does not identify a species by itself. Two names can share the same range, and one encounter value can sit inside several card bands. Confirm the result name after the catch.
Documented Bluestone bands
The current public list includes several Bluestone ranges: Fungstone at 52.5–87.5 Hz; Flintcap and Quartzbud at 78.7–131.2 Hz; Gemscroom and Nightcap at 93.7–156.2 Hz; and Crystallina and Trufflecrust at 217.5–362.5 Hz. Other Bluestone names remain without a reliable public range in the same list.
Leave an unsupported range blank. Copying a neighboring species’ band or inventing a value from rarity can send a player into the wrong instrument purchase. The high Crystallina/Trufflecrust band also illustrates why later-region hunts can require a stronger Resonance tier than the opening tools.
Match frequency with Resonance
Resonance is the instrument field most directly associated with reachable frequency. The free Wooden Lute is reported at Resonance I, early Grove purchases at low Resonance tiers, and later Bluestone tools at higher tiers. Community sources disagree on a few launch cards, so open Equipment Bag → Instruments and read the card you actually own.
Do not reduce the decision to Resonance alone. An instrument can reach a band and still feel difficult during timing, tuning, or catch-zone control. Tune Speed is explicitly connected to the speed of the tuning stage in the official description. Precision, Harmony, Tension, and Luck appear on instrument cards, but their exact live behavior should be taken from current tooltips and repeated play.
Use the instrument stats guide to diagnose which printed field matters to the stage you are failing. Use the instrument list to see which tools are purchases and which are quest rewards.
Perform the tuning stage
- Equip the catching instrument before approaching the Scroom. The Ocarina is a world-interaction tool, not a replacement for the catch instrument.
- Start playing close enough to draw the target into the encounter.
- Complete the opening timing input shown by the game.
- Hold and drag the frequency control instead of tapping randomly across the full bar.
- Watch the waveform or alignment feedback and make smaller corrections as it smooths.
- When the game advances, move to the catch-zone stage and keep the target inside until progress fills.
If the control never reaches the visible target, check instrument Resonance before assuming your timing is wrong. If it reaches the target but settles slowly, compare Tune Speed. If tuning succeeds and the progress bar drains later, the problem is catch-zone control rather than Hz.
Frequency is not a spawn rate
Hz is a tuning measurement attached to the encounter. A band of 18.7–31.2 Hz does not mean an 18.7% or 31.2% appearance chance. A wider band does not prove that a Scroom is more common, and a higher band does not automatically mean a higher rarity.
Do not combine the number with badge award percentages to calculate odds. Badge rates describe how many players earned an achievement among a changing population. They are influenced by progression, skill, playtime, and quitting, not only creature availability.
Build a reliable hunt note
For each target, record the base name, current area tab, rarity, displayed Hz band, equipped instrument, Resonance, date, and result. Add a prefix only when the catch screen shows it. This lets you compare changed values after an update without confusing a variant with a new base species.
If two sources disagree, mark the range as community reported and use the live card. Do not average the numbers. A card update is not improved by inventing a midpoint between old and new values.
Troubleshooting
The waveform keeps sliding past the target. Make smaller movements and release unnecessary camera input. If your instrument has a low Tune Speed, allow the control time to settle.
The target is outside the slider’s useful reach. Check the Index band and instrument Resonance. Move to a higher-reach tool instead of repeating the same attempt.
The frequency looks correct but the catch fails. Frequency is only one stage. Keep the Scroom inside the moving catch zone; the official description says progress drains outside it.
A guide lists a different range. Compare dates and the live Index card. Prices, cards, and values can change, and some sources copied pre-launch footage.
The Index still shows a missing variant. A successful base catch may not fill Harmonic or Resonant slots. Confirm the result prefix and the specific slot that changed.
FAQ
What frequency is Redcap?
The checked Index reading lists Redcap at 18.7–31.2 Hz. Use the live card if your server shows another value.
What frequency is Koroom?
The checked Grove list places Koroom at 71.2–118.7 Hz, the same reported band as Burlcap. The shared band does not make them the same rarity or spawn.
Does higher frequency mean rarer?
No. Frequency, rarity, and spawn availability are separate. The Grove list contains shared bands across different tiers.
