108 notes

A searchable reference table mapping note names (like C4), MIDI note numbers, and frequencies (Hz). Useful for composing, checking synthesizer tuning settings, or confirming a note number in a DAW.

How to use

  1. Type a note name (e.g. A4), MIDI number, or frequency into the search box.
  2. The table filters in real time as you type.
  3. Check the corresponding note name, MIDI note number, and frequency.

FAQ

What frequency is A4?

Under the standard modern tuning reference, A4 is 440 Hz โ€” this table calculates all frequencies from that reference.

What is a MIDI note number?

A number from 0-127 assigned to each pitch under the MIDI standard, commonly used to specify notes in music production software.

Is this useful for checking synthesizer tuning settings?

Yes โ€” quickly look up the frequency (Hz) for a given note name as a reference for manually tuning a synthesizer or oscillator.

Is this useful for specifying a MIDI note number in a DAW?

Yes โ€” when entering a note number directly in a DAW, use this table to check which note name it corresponds to.

Can I look up a note name from a frequency?

Yes โ€” type a frequency value into the search box to see the note names with the closest matching frequency.
