The cork on the tenon joints can be covered with special caps to protect the wooden body of the flute from cork grease. The important grease stays where it belongs and does not spot or effect the bore or cleaning cloths.
The cups, which were originally cast then finished, are now turned out of one solid silver piece. They are stonger and more stable than before.
The adjustment of the cork is one of the most important elements for sound quality and intonation. Now the cork has been calibrated to be set in the most ideal place. Additionally, after turning the crown, it is possible to turn it back to its optimum setting.
The thumb system is now more stable and is constructed using two tubes.
The thumb system in profile: one fixed axis with two tubes turning around.
The new thumb system makes it possible to bring this part of the keywork closer to the main system on top of the flute. The result is a more advantageous and ergonomic balance of the flute in the hands.
The new flute cases are stronger and covered with the finest quality leather.
The sound of an Alfred Verhoef flute is determined by the specific wood of that flute and its various measurements. All the measurements are equal with the exception of the diameter of the instrument, which is determined each time by the specific properties of the wood which is used.
When a flute is ready to play, I make tiny changes to the blow-hole and bore until the flute begins to sing and the optimal sound is there. As a result of this, every flute is unique and there is no ‘standard’ AV flute. All the keywork is built to fit each particular flute , with the precision needed to fit the diameter of each instrument coming from skilled handiwork.
As a flute maker I am always aware that there are matters which could be improved. Technically, new developments could lead to the keywork becoming stronger, more stable or more ergonomical, helping to aid a flutists posture. It might be possible to enhance the colour or the purity of the instrument further. The pictures above show the latest developments I have made to my flutes. Some aspects of these developments are explained further under ‘Making Flutes’.
