Majora's Mask Heart Pieces
This guide shows the locations of the 52 Heart Pieces from the Nintendo 64 version and the Majora's Mask 3D Heart Pieces from the Nintendo 3DS version. 51 of the 52 heart pieces are roughly in the same exact location. However, in the 3DS version of the game, the game flip-flopped the location of one Heart Piece with an Empty Bottle. Either way, using this guide will get you all 52 heart pieces, regardless of what version you are playing. This guide more or less is in the order when the heart pieces are first available. In many cases, while you can get a heart piece at that time, it isn't always the most convenient.
Majora's Mask features 52 heart pieces scattered across Termina, offering 13 Heart Containers to Link's total health.

What makes this so difficult is that not only do you have to stop the timer on exactly 10 seconds, but the timer will disappear from the screen after the first couple of seconds.

Heart Piece N64: Go to the Swamp Tourist Center and speak with Koume after you've defeated Odolwa and rescued her earlier. She will let you play a little game now that the poison is clear. Koume will fly around on her broom, holding a target below her. The object of the game is to hit the target at least 20 times. You can hit her 10 times and then you're out. Aim carefully, it is pretty easy. Once you've done it, you will receive a Piece of Heart as a reward.
This is changed in the 3DS version of the game. Instead of receiving a Piece of Heart as a reward, you receive an Empty Bottle. The location of the Piece of Heart is swapped with the location of the Bottle you receive in Ikana Graveyard.

Conditions: Acquire the Mask of Truth (Recommended)
Heart Piece #19: Go to Mamamu Yan's Doggy Racetrack at the back of Romani Ranch. You have to bring her a dog to race with and bet a certain amount of Rupees to play. If you win 150 or more Rupees, you will receive a Piece of Heart. Before you actually pick a dog to race with, walk around picking them up one by one while wearing the Mask of Truth. With this, you can hear their thoughts.
When you find the one that says something to the extent of "Ruff! There's no way I can lose!" and is very enthusiastic, take him and bet 50 Rupees on him (the maximum amount). The races are pretty random, but it is a very good chance that you will at least get third, which will still allow you to keep your Rupees. If you don't get it the first time, find the correct puppy that makes the above statement and do it again. After a few tries you will get it. You could get this without the Mask of Truth, but you'd be picking blindly.
