If you are looking to expand your instrument choices for Primary (or at home), consider some Pipe Chimes. You can find them here: Musical Pipes
This page will send you to an Etsy shop where you can build your own set to fit your own budget and needs.
I purchased my own set last year after spending an arm and a leg on 2 sets of hand bells. I decided that I love the Pipe Chimes more than my hand bells. Here are some reasons why I think Pipe Chimes are better:
1) Price. Pipe Chimes cost way less than a set of handbells. You can also build your own set. A basic set includes 23 chimes for $30.00. Add $5 for 14 metal strikers. A 13-note hand bell set goes for $67.00 on Amazon.
2) Durability. These chimes are basically indestructible. I always worried about the kids touching the ringer or pulling the spring on the hand bells. I don't worry about them destroying the chimes. They are nice and sturdy.
3) Easy to play. Pipe Chimes are easy to play. Hand bells are tricky. You have to ring them "just right". Pipe Chimes are easy for little hands and it doesn't take a lot of coordination to make them sound good. Even the little kids in nursery can play them. (I don't organize a song for them to play, but they just love banging them.)
4) Range of notes. The Pipe Chime set includes 23 notes. It allows for a lot more participation and a better selection of songs to play. Hand bells are tricky if you don't have the right bells or enough bells or the song isn't written in a certain key.
5) Songbooks. The Pipe Chime website offers songbooks for $10 each if you prefer a printed copy, or for $3 for a digital copy. I find the digital copy very helpful in Primary for displaying through a projector. This allows for the children to see well and follow along easily. The songbooks are your own little "bell charts" without the work to create one. They are already done for you.
6) Made for LDS use! There are different songbooks available for purchase including LDS Primary Songs, LDS Hymns, and Christmas songs. There are also 2 other books available of other songs. There are also a few "other" songs available for download on their website for free like, "I Know That My Savior Loves Me".
7) One-Man-Band option. If you would like only one person to play multiple chimes, Pipe Chimes offers the option of purchasing "holders" for the chimes that allows you to lay the whole set out on a table. I love this option for a descant in songs like "Christmas Bells Are Ringing".
8) Easy to transport. Throw them in a bag and off you go. Hand bells need to be stored carefully in a bulky box to keep them from getting ruined. Pipe Chimes don't take up a lot of space and kids can help put them away.
9) Not just for Primary. My family has started a new tradition the past 2 Thanksgivings. After Thanksgiving dinner, we sit together, pass out Pipe Chimes, and sing and play Christmas songs out of the Christmas songbook. We have so much fun together. My mom has purchased 2 sets to accommodate our large crowds of family (close to 50 people). This has been my favorite part of Thanksgiving the past 2 years.
I hope this helps and I hope you check them out. They would be a great addition to any Primary and/or home.
