Usefull info for the composer:
If you are a composer and you are going to write for the Aluphone you can find some advice here. The Aluphone comes in different sizes and the most used is the Glennie Concert without a dampening pedal. It is a 2 1/2 octave instrument with the range from G4 – C7. You can think of it as almost the range of a vibraphone, but one octave higher. The sound can change a lot, depending on the types of mallets you are using. Soft mallets gives you the sound of Tebetian Singing Bowls, medium hard mallets give you more of a vibtaphone/bell sound and hard mallets make the Aluphone sound almost like church bells.
Glennie Bass is a smaller version from C4-G4. It can work as a bass extension.
The Aluphone is easy to bow, it has a very fast attack and the sound is like a glass spiel. The sound is one octave above the fundemental.
You can play the instrument with almost any kind of mallet like rubber, wood, plastic and metal. Tuning A = 442
The tuning of the Aluphone:
The unique sound of the Aluphone occurs because of special overtones that differ from the overtones you know from a piano. On a piano, the tone is basically formed by a mixture of the fundamental and the overtone, which is an octave plus a major third over. This sound is what our ears perceive as normal, and a sound you would think is in tune.
An Aluphone has a very particular overtone, which is located between a minor third and a major third one octave above the fundamental. The overtone is also very powerful and it affects the experience of the keynote. This provides the unique sound. The overtone of the instrument is not tuned, and that is what gives it the distinctive sound of a bell. Church bells also have overtones that are not tuned. For some harmonies it is perceived more clearly than in others especially in the low register. In the high register you dont hear the overtones very much, because the overtones are way up. Aluphone has chosen not to fine tune the overtones of the bells, as it will affect the instruments characteristic sound.
