Basic 301 Redirect code not working - .htaccess

Question

My pages are not redirecting for some reason. I'm trying to use the below code in my htaccess file.
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
RewriteEngine On
Options +FollowSymLinks
RedirectMatch 301 ^/([^-]+)-([^-]+)-([^-]+)-([^-]{2})\.html$ /$1-$2-in-$3-$4.html
RedirectMatch 301 ^/([^-]+)-([^-]+)-([^-]+)\.html$ /$1-$2-in-$3.html
# 301 --- http://www.domain.com/music-classes-san-diego-ca.html => http://www.domain.com/music-classes-in-san-diego-ca.html
RewriteRule ^music-classes-san-diego-ca\.html$ /music-classes-in-san-diego-ca.html? [L,R=301]
The 301 redirect is what I'm trying to get to work. It's not redirecting for me. I've also tried this:
redirect 301 music-classes-san-diego-ca.html http://www.domain.com/music-classes-in-san-diego-ca.html

Any time you are using wordpress, those rules always needs to go last because it routes everything to index.php. Try your rules before wordpress rules. FYI, I personally would use Rewrite for all 301's and not mix them with RedirectMatch.
