Show HN: Let's Bend - Open-Source Harmonica Bending Trainer
Hi HN, I built a simple harmonica practice app that shows real-
time pitch and bending targets for each hole. It helps blues harp
players visualize their technique and improve intonation. No
tracking, no ads, open source (MIT). The app is available on
F-Droid and GitHub. You can find more details here:

| Bending takes a bit of practice but it's not terribly hard. Here

|
| 1. Don't start with a wooden harp like marine band. The metal and
| plastic ones are typically a bit easier to bend.
|
| 2. One hole at a time. Ensure you can exclusively blow in a
| single hole to practice
|
| 3. Lower notes are generally easier to bend than higher notes
|
| 4. Make an O with your mouth and have the tongue float in the
| middle. Start by pulling, not pushing, in my experience bending
| on intake is slightly easier than bending on blowing out.
|
| 5. Tighten the lips and decrease the size of the O to increase
| pull force on the reed to create a bending effect, and also
| tighten the airflow chamber above your tongue by pulling your
| tongue back and up, then loosen it by moving your tongue forward
| and down
|
| This tool looks great for helping improve once you've been able
| to perform the initial bend. Excited to try it out!

|
| Additionally, you'll probably find a lower key harp to bend
| better, at least to a point. I feel like an A harp is the sweet
| spot for bending really well without being so low that it
| starts becoming difficult. G harps are good too, but require
| you to dig deeper to get a good bend.

| You start by playing clear single notes and then shaping the note

| Little Walter's greatest hits on my hour long morning commute,
| and eventually it was just natural to bend the notes at the right
| time. My advice is to look for Jason Ricci on YouTube. He has
| hundreds or thousands of videos on beginner to advanced subjects.
| He is a weird dude, but I've never known a better teacher.
