Vowel Proportions

Distribution of the eight German vowels (a, e, i, o, u, ä, ö, ü), counted case-insensitively. The centre of the chart shows the overall vowel share of all character tokens in the selected archive. Use the selector to compare the full corpus against individual archives. For per-song variability of the five base vowels see Vowels Distribution; for the overall vowel share relative to consonants see Consonant-to-Vowel Ratio.

Linguistic Insights

Phonoaesthetics and vowel preference

Vowels sustain the acoustic signal in singing, whereas consonants interrupt airflow. High vowel density increases singability and directly shapes melodic phrasing. In German, this phonetic landscape is heavily dominated by 'e'. One caveat: elision is pervasive in sung German — ich geh', hab', gibt's — and each dropped vowel letter shifts the distribution slightly.

Umlaut proportion as a lexical indicator

The umlauts ä, ö, and ü occur primarily in native German words. Consequently, their combined proportion among vowels serves as a simple metric of how distinctively German the lexis is.
