All major scales use the notes of the musical alphabet in order; no notes are skipped and no notes occur twice. In the example above, the first four notes are $\text{D}$–$\text{E}$–$\text{F}^♯$–$\text{G}$, not $\text{D}$–$\text{E}$–$\text{G}^♭$–$\text{G}$. In $\text{D}$–$\text{E}$–$\text{G}^♭$–$\text{G}$, $\text{G}$ erroneously occurs twice and the $\text{F}^♯$ between $\text{E}$ and $\text{G}$ is skipped.
