You can see a low-frequency peak but do not know its note, role or relationship to the bass.
Kick Frequency and Note Calculator
Convert kick notes to hertz or hertz to the nearest note, inspect harmonics and cycle time, and understand what the number means for kick-and-bass decisions.

A kick is often a pitch journey, not one note
The onset of a synthesised kick may fall rapidly from a high starting frequency into a more stable low tail. An acoustic kick adds resonances, beater noise and room energy. A spectrum analyser can therefore show several peaks that do not all represent a stable perceived note.
Use the calculator after identifying which region is sufficiently stable to matter. The fundamental is useful for understanding register and bass relationships; harmonics help explain why the kick remains audible when its deepest frequency is not reproduced.
What to listen for
- A stable tonal centre in the body or tail rather than the first few milliseconds.
- Whether the second and third harmonics carry identity on smaller speakers.
- Whether tuning improves the groove or only makes the analyser look orderly.
- How the selected note interacts with more than one bass note.
Questions producers ask
Frequently asked questions
Does every kick have one musical note?
No. Many kicks have a falling pitch envelope, noisy onset and a tail that becomes more stable. Measure the part that is actually tonal rather than forcing the whole sound into one note.
What frequency should a kick drum be?
There is no universal frequency. The useful fundamental depends on the source, genre, bass role, playback system and how much of the pitch is stable enough to perceive.
Should the kick and bass be tuned to the same note?
Not automatically. Matching can reinforce or crowd the low end. Timing, envelope, register and harmonic content can matter more than exact note matching.
What does cycle time tell me?
Cycle time is the duration of one waveform cycle at the selected frequency. It helps explain why deep low frequencies respond slowly to very short fades, offsets and timing changes.
