The Aidoni grenadilla barrel is the result of a long and meticulous process of experimentation. It has been co-created by Martin Fröst over a four-year period. Since 2016, Martin uses Aidoni grenadilla barrels on all his clarinets.
The barrel has an inner plastic tube with a reverse taper, and the tube is partially covered with a thin brass pipe. The result is a perfectly balanced barrel with exquisite intonation, and a resonant and focused sound. The use of a plastic inner tube allows a precisely measured bore, keeping its dimensions constant. The Aidoni barrel reaches the right temperature and pitch faster than a traditional wood barrel. The Grenadilla wood produces a warm and solid sound, and the clear projection makes it suitable both for orchestra players and for soloists.
