I've been playing tin whistle for several years now. I grew up listening to Irish music, but didn't start playing until I was 15 or 16 (I'm 19 now). I started out with a cheap generation D and worked my way through tunes that I knew from albums I own. I'm not sure I'd reccomend this approach, as I basically dove right into the fire, learning advanced tunes like "Kid on the Mountain" (I started by learning the tunes from my favourite traditional album, a live recording by the Bothy Band.) I picked up fingering pretty fast and soon I was able to play tunes in-tempo with the recordings I was learning from. Unfortunately, since I was teaching myself and learning by ear, I picked up bad habits in trying to immitate the advanced ornementation techniques I was hearing on record. Only later did I buy a Irish whistle guidbook, "The Tin Whistle Toolbox" by American flute and whistle player Grey Larson, that I learned proper ornementation techniques, like cuts and strikes and rolls. In the process I had to go back to the basics and play the tunes very slowly, paying attention to rhythm and percisioin. So if you're starting out, my advice is to learn simple tunes by ear and work them through slowly until the fingering has become ingrained in your head, but don't try to play them at the same tempo as on recording until you are able to keep steady tempo, and most importantly, don't try to do ornamentation by ear - get a book that teaches you how to do it properly, or have a more advanced player teach you in person. Most tunes are fairly easy and straightfoward to learn, but mastering proper ornamentation takes time and patience. Of course, playing Pogues stuff doesn't require much of that because in the ensemble setting, all you need to do is carry the melody. But when it's only the whistle, having good ornamentation is key and it is easy to tell an experienced player from a beginner and even easier to tell if the person has taught themselves improper techniques and is trying to pass it off as advanced playing, like I was doing a couple years back. Although it's one of the easiest istruments to pick up and work out a basic tune, like any instrument, the whistle takes time to learn to play well.
damn, I've written a lot - sorry to go on so long, hope it's been helpfull. Last thing I'll say is that if I had to recommend a whislte to start out with, I'd go with Susato (my current brand of choice to play at sessions, where it's important to be heard above the other instruments, as my good quality Copeland is too soft for sessions but great for playing on its own.) Susato is more expensive then Generation and Clarke but it's not high end. they have a good, loud shound and are tuneable, with removeable head pieces. Because they're comparatively cheap, I've been able to buy Susato whistles in a number of different keys, which is perfect for the weekly sessions I play in. Cheap whistles are not very good quality, and I think that Susato is much easier to learn on then generation, because it has a wider bore and a thumb rest. I also own an Overton low F whistle which is about 15 years old (given to me by an uillean-piper friend who I play with) and it still sounds amazing. Perfect for gorgeous slow airs, and I'm also getting better at playing faster tempo tunes on it, although it's more difficult then smaller whistles and its low pitch is no good for playing in sessions. I would like to purchase an Overton high D, especially now knowing it's Spider's choice
Also, tin whistle albums to check out: Mary Bergin's Feadoga Stain is one of the most important whistle albums to be released in the last 25 years. Also, Joanie Maddon of Cherish the Ladies, Paddy Moloney of the Chieftains, Seamus Egan, John McKenna, Grey Larson, Paddy Taylor, Matt Molloy (actually, some of these are more flute players, but there's overlap), Kevin Crawford, Sean Ryan, Willie Clancy, Seamus Ennis and many others...
ive gone off long enough, hope this was helpful
ps. Spider, you're the man! I was up front near the stage at Brixton last December and seeing you play up close was fucking brilliant. I wish you would sing Drunken Boat at the reunion shows - one of my absolute favourite songs the Pogues ever did (but Tuesday Morning's fantastic too!)
peace.
I could've been someone...
