Karenna Caun is a medical doctor in addition to being a trained singer from the Royal Northern College of Music. She has written the following extract on the Grindea Technique which you can view at the ABRSM website.
“The Grindea Technique (18) was developed as a pre-performance tool to help
release tension and achieve mental focus. It was formulated by Carola
Grindea, a pioneer in this field and Chairman of the International Society for the Study of Tension in Performance (ISSTIP). My view is that done regularly
it may also help to correct longstanding postural misalignments and build
general awareness of muscle tension and its release. The technique is described
1. Raise your shoulders right up to your ears. Tense, then release, letting everything go. Repeat twice more. Take care not to jut your chin out or back and keep it level.
2. Put your arms out straight in front of you with palms facing each
other. Tense. Lift your arms above your head until they are beside your
ears, parallel and with palms still facing. Then lower your arms to shoulder
height with the palms down… still tense. Imagine that you are trying
to touch the walls either side of you. Then release, letting everything
go. Repeat once more. Take care not to jut your chin out or back and keep
it level. Try not to arch your back. The following steps should be done
with the eyes closed. It is important that you don’t try too hard, rather give
your body the instruction mentally and then allow the effect to take
place. Trust your body to sort itself out.
3. Let you neck be free.
4. Give your spine an order to lengthen and straighten in an upward direction. Give it time.
5. Imagine your head is like a balloon which floats off and hovers above your lengthened, floating spine.
6.Let your jaw lower and with open mouth exhale quite noisily three times, letting your tensions go out ‘through heavy hands’.
7. Let your knees and ankles feel like clouds – so they still support
you but are not locked.
8. Open your eyes again!
Parts 3 to 7 are really the crucial part of the technique and can be done at almost any time and almost anywhere!”
