We consider a « traditional organ » as being an instrument with the following features:
Organs built according to these principles are reliable, have a long life and require little maintenance. With their timeless design they are most likely to outlive changes in trend.
From a musical point of view they amply meet the needs of the vast majority of parishes. Individual organs with these features can be built more rigidly based on historical models and can aid historical performance practice as style copies.
Although we continue to stand true to traditional principles, we take the arguments against these principles seriously. Individual Metzler organs can therefore be found which incorporate certain technologies and tonal ideas which had, in previous decades, been avoided (double registration, symphonic voicing, modern case design).
This stylistic broadening of our horizons has certainly proved to be a fruitful experience: certain achievements have, on the one hand, had a positive influence on our traditional organs and, on the other hand, enable us to take up new challenges.
