Singers who perform German songs (Lieder) or opera often find the language harder to sing than Italian or French. Online courses on German diction try to help, and they range from short lessons to long programmes. This guide describes what one university course on the subject covers, then lists what to check before paying for an online course. It is general information, and no course can promise a particular result: how your diction improves depends on your starting point, your teacher and your practice.

We have not tested any course named here, and we do not say any course will improve your singing.

What a university course covers

Source: NYU Steinhardt, course page "German Diction for Singers" (steinhardt.nyu.edu/courses/german-diction-singers). Read in a browser. Last checked: 19 October 2026.

The course page describes a one-credit course that includes further study of the International Phonetic Alphabet (IPA) symbols as they apply to German, and the rules for lyrical pronunciation of standard German (Hochdeutsch). Students transliterate song texts into IPA and demonstrate mastery of the diction rules through performing assigned repertoire. The page lists no prerequisites.

That gives you a yardstick for any course: does it teach the sounds with IPA, does it explain the rules, and does it make you apply them to real song texts?

Before you pay for an online German diction course

  1. Check the level. One example, the German Diction Master Program, says on its page that it suits singers who are studying classical voice, have completed a vocal degree or already perform, and who want to perform German Lied or opera. If you are a beginner at German or at singing, check that the lessons start where you do.
  2. Read the topic list. That page lists body positioning for free articulation, tongue and jaw exercises, the soft "ch" sound, clear pronunciation without lip tension, and analyses of texts such as an aria from Mozart's Magic Flute and the song "Frühlingsglaube". Compare this with the yardstick above: the page we read does not mention IPA, so ask whether the course uses it.
  3. Check the format and length. The page describes a self-paced course of "10+ lessons" as instructional and practice videos, with no total duration given. Ask how many hours of video you get.
  4. Check the price and currency. The page lists the price in euros: 500 euros at the standard price, with payment in instalments available. Prices, codes and discounts change, so read the checkout page and convert to your own currency before you buy.
  5. Find the refund terms. The page we read had no refund policy or guarantee. Look for it at checkout, and ask the seller before you pay if it is not stated.
  6. Check who teaches. The page names the author and describes his background. Qualifications on a sales page are the seller's own statements, so look for independent evidence such as a teaching post or published recordings if that matters to you.
  7. Treat testimonials as opinions. The two on that page are not independent reviews. Promises of an "effortless" result are marketing: diction improves with practice.
  8. Compare with other routes. A teacher or coach who can hear you, a university or conservatory course, or a printed diction guide with an IPA chart may suit you better, because you can get feedback on your own sound.
