New Answer
This answer now uses the Singapore theme, (downloaded from here) and a proper definition of fading.

I made the header slightly larger, such that it contains the frame title.

Old Answer
Sorry, this answer does not use the Singapore theme, but a custom headline (which I actually prefer to the Singapore one).
I have combined answers from here and the tikz
-manual (20.3 Fadings, page 236f). I think I am not properly setting up the \shade
rectangle, as there is a small gap on the right side. Better use the \tikzfading
from above.
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{fadings}
\setbeamercolor{secsubsec}{fg=orange,bg=black}
\begin{tikzfadingfrompicture}[name=fade bottom]
\shade[top color=transparent!0,
bottom color=transparent!100] (0,0) rectangle (2,2);
\end{tikzfadingfrompicture}
\setbeamertemplate{headline}
{
\leavevmode%
\hbox{%
\begin{beamercolorbox}[wd=\paperwidth,ht=8.25ex,dp=3.5ex]{secsubsec}%
\raggedright
\hspace*{2em}%
{\sffamily\Large\color{orange}\thesection.~\insertsection\hfill\insertsubsection}%
\hspace*{2em}%
\end{beamercolorbox}%
}\vskip-0.5pt%
\hbox{%
\tikz\fill[path fading= fade bottom, black] (0,0) rectangle (\paperwidth,0.5);

Full code
Above you have two approaches:
myblock
)mytblock
)The
tcolorbox
package already has a built-intitle style tile
that will let you insert any background picture and tile it for you. Note that in the MWE I used a big picture (like 600x480) which was already tiled by itself and so I had:If you have a non tiled picture, the first variable would specify the width of a single picture, so you'll have something like
Since you're using the Singapore theme a similar result can be achieved by hacking the beamer block template. As you can see the code is more complicated (a bit hackish) and in this case you need to use an already-tiled picture like mine (unless you want to complicate things even more).
you can find the hearts picture here.
