Jazz Euphoniumist Tom Ball compiled a free set of recordings with an
accompanying booklet to help players develop a good ear for intonation.
In his words:
"It is a series of 2 minute drones on all 12 chromatic pitches.
It is a great tool for practicing pitch matching,
interval tuning, tune scales, chords, improv, etc.
I have also posted a booklet about just/even tempered tuning
explanation and some ideas on how to use the drones.
You will need to download each track separately.
They are in Mp3 format. The booklet is in PDF format.
I hope people will find this tool useful and enjoyable to use.
Similar products are on the market for $20 or more.
I thought it would be silly to charge money for this
because it was so easy to make."
