theres a couple flicker of notes that would be impossible to recreate with the town tunes system, but this is as close as i could get it. it probly won't sound that great or how you want it to sound.   

A(orange), G(yellow, A(yellow), C(dark orange), rest, A(orange), rest, E(red), D(dark orange), hold, hold, C(orange), hold, hold, hold.

...actually, after testing it, it sounds pretty close. just in case you don't know, a rest would be setting the little frog all the way down, or off. and a hold is one click above the rest, which would be the purple with the "-" 

you can get one from Isabelle at the town hall. when you talk to her at the front desk, select "advice for living". i believe she tells you about writing a letter, so go out and send one. go back to her and select "advice" again. she'll suggest going to the beach and bringing her back a shell. so go get her one and bring it back. once again, select "advice" and she'll talk about fishing and bug catching. if you have a fishing pole but not a net, or vice versa, select the one you dont have and you can get that tool from her. complete everything she says to do when you select "advice for living" and she'll say she doesn't have any more advice, and she'll then give you a watering can as a gift. also, if you spend 12,000 or more at nookling junction and 7 or 10 days has passed since getting the game, nooklings will upgrade to a bigger store and a garden store will open up next door where you can buy water cans and axes and stuff

Look no further than the greatest game series EVER (unless you've already played it) ...HALF LIFE 2.  Greatest story ever in a game, and gameplay as well. Perfect for playing small or big increments at a time. It does saves states instead of traditional saving, so you can literally be right in the middle of a battle, pause and save, then reload the save state, and you will be standing right where you left off, as if you just paused the game. And the best part is theres no cutscenes in the whole game. You're free to move about and pay attention at will to dialague and important storytelling. And you can still do save states during dialogue/storytelling, so if you need to stop playing right away, you can leave off right in the middle of an important part without missing anything. Anyways, its proven as one of the greatest games of all time. My 3 favorite games/series ever are Zelda, Half life, and Shadow of the colossus. Just pick up a copy of the Orange Box if you haven't already experienced Half life.

i've always had trouble with using the standard battery method. the factory battery packs must not have tight enough tolerances in it or something. ever since i switched to aftermarket rechargeable battery packs, i haven't had a single problem. i've been using the Energizer rechargeable packs and dock kit for a long time, and its by far the best.
