Sådan læser du akkordformler

En akkordformel beskriver, hvilke intervaller en akkord stabler på sin grundtone. En durtreklang er 0–4–7 halvtoner (grundtone, stor terts, ren kvint); en moltreklang sænker tertsen: 0–3–7. Septimakkorder tilføjer en terts ovenpå: Cmaj7 er 0–4–7–11, C7 er 0–4–7–10.

Den samme formel virker fra enhver grundtone: transponér halvtoneafstandene til en anden grundtone, og du får den samme akkordtype i en anden toneart. Brug denne tabel sammen med skalasiderne for at finde ud af, hvilke akkorder der passer til en toneart.

Ofte stillede spørgsmål

Hvad er en akkordformel?

En akkordformel er den række af intervaller, sædvanligvis angivet i halvtoner eller skalatrin, der definerer en akkordtype uanset dens grundtone – for eksempel dur = 0–4–7 halvtoner (1–3–5).

Hvad er forskellen på C7 og Cmaj7?

C7 (dominantseptim) bruger en lille septim: C–E–G–B♭ (0–4–7–10). Cmaj7 bruger en stor septim: C–E–G–B (0–4–7–11). Forskellen på den ene halvtone ændrer fuldstændig akkordens funktion.

Hvordan bruger jeg akkordformler på andre grundtoner?

Læg de samme halvtoneafstande til enhver grundtone. En moltreklang (0–3–7) fra A giver A–C–E; fra F♯ giver den F♯–A–C♯. Akkordtypen forbliver den samme, kun tonehøjden ændrer sig.
