Cara membaca rumus akor

Rumus akor menggambarkan interval mana yang ditumpuk sebuah akor pada not dasarnya. Trinada mayor adalah 0–4–7 semiton (dasar, terts mayor, kuint perfek); trinada minor menurunkan tertsnya: 0–3–7. Akor septim menambahkan terts di atasnya: Cmaj7 adalah 0–4–7–11, C7 adalah 0–4–7–10.

Rumus yang sama berlaku dari not dasar mana pun: transposisikan pergeseran semitonnya ke not dasar lain dan Anda mendapatkan jenis akor yang sama dalam kunci berbeda. Gunakan bagan ini bersama halaman tangga nada untuk menemukan akor mana yang cocok dengan sebuah kunci.

Pertanyaan yang sering diajukan

Apa itu rumus akor?

Rumus akor adalah kumpulan interval, biasanya ditulis dalam semiton atau derajat tangga nada, yang menentukan jenis akor terlepas dari not dasarnya — misalnya mayor = 0–4–7 semiton (1–3–5).

Apa perbedaan antara C7 dan Cmaj7?

C7 (septim dominan) menggunakan septim minor: C–E–G–B♭ (0–4–7–10). Cmaj7 menggunakan septim mayor: C–E–G–B (0–4–7–11). Selisih satu semiton itu sepenuhnya mengubah fungsi akornya.

Bagaimana cara menggunakan rumus akor pada not dasar lain?

Tambahkan pergeseran semiton yang sama ke not dasar mana pun. Trinada minor (0–3–7) dari A menghasilkan A–C–E; dari F♯ menghasilkan F♯–A–C♯. Jenis akornya tetap sama, hanya nadanya yang berubah.
