Notasi tala ilmiah
Tabel frekuensi nada

Tabel di bawah ini memberikan notasi nada berdasarkan frekuensi tuts piano standar: nada konser standar dan temperamen setara dua belas nada . Saat piano disetel hanya pada intonasi, C 4 merujuk pada tuts yang sama pada keyboard, namun frekuensinya sedikit berbeda. Tuts yang tidak muncul pada piano mana pun (abu-abu sedang) atau hanya pada piano 108 tuts yang diperluas (abu-abu muda) akan disorot.

Secara matematis, jika diketahui jumlah n seminada di atas C tengah, frekuensi dasar dalam hertz diberikan oleh  440\cdot 2^{(n-9)/12} (lihat akar kedua belas dari dua ). Mengingat nomor MIDI NoteOn m, frekuensi nadanya normal  440\cdot 2^{(m-69)/12} Hz, menggunakan penyetelan standar.
