Tin whistle XIV (English)

It's been difficult!
Through all this time I have tried to add up new things to what I already know - namely, the "embelishments" I talked about - but it seems things don't work out. Alright, I haven't practiced as much as I should, but I should have succeeded in at least one or two things.
What is more, my tinwhistle doesn't help me much anymore. In spite of having played it only for 11 months, the sound is no more the same, and that's a nuisance sometimes; the tune doesn't sound good.
I need to buy a new tinwhistle, a nickel-plated Generation or a Walton's Little Black D, maybe. While that doesn't happen, I'll go on with my "old" Claire anyway. :)
